@MarioDConti3 years ago Great job. Got to the point quickly. Your calculations made it clear why fuel cells haven’t bene used broadly yet.
@

@GabrielDeVault3 years ago One of your best videos yet! I think one aspect you missed right at the end was when you compared cost of Fuel Cell to Battery. Yes, a Fuel Cell system is likely to cost more initially. But Fuel Cell systems can be used for more than 10,000 hours, some as high as 30,000 hours or more. Most batteries will have to be replaced at just 1-2k hours of use. ... 8

@grantschlichting46313 years ago As you mentioned near the end of the video, you said it's dependent on the amount of hydrogen that can be carried - if you could do a video on hydrogen storage, I think that could be really interesting as that is a limiting factor. For instance at 700 barr, there is only 5 kg of hydrogen for a 95 kg container ... 13
@

@kevenc2 years ago Great summary, but from all my research, the energy density of hydrogen, even with fuel cell weight, is much higher than batteries. Otherwise there would be little reason to consider it. Maybe you're talking about peak power? I agree about the round trip efficiency. Hydrogen seems like a stop gap measure until battery energy density catches up. ... 1

@LeonRamkumar3 years ago Great video as always. I think the cost at this point is moot really, as most of the established players are looking to divest from fossil fuel planes. Not only is the cost of Aviation Fuel higher, but consumer's demands for a more sustainable model are also quite relevant. If you add the European Union, Japan and South Korea's push to a Hydrogen infrastructure into the mix, adoption seems guaranteed. ... 7

@jones37813 years ago Have you looked into Advent Technologies high temp fuel cell? If so, please do a video on your findings. 2
@

@ddegn3 years ago I don't think fuel cell have to be price completive with batteries if they can offer much higher energy densities.
I think energy density will be the driving factor in determining which power system prevails as a fossil fuel alternative in aviation.
Thanks for another interesting video. ... 13

@jefferee20023 years ago Problem most, if not all the hydrogen we currently get is from fossil fuel sources. Until that changes they may as well stick with jet fuel 7

@stevenbalderstone7093 years ago Is there potential to use super-capacitors in conjunction with fuel-cells for the high-energy demand phase of flight for eVTOLS?: i.e. during take-off. The fuel-cell could charge the super-capacitors prior to take-off. 1
@

@peterwei3 years ago Combined with super capacitors may be even more efficient with the addition of a smaller battery to enable a cold start. 2
@

@Kawitamamayi3 years ago Have you addressed the potential for low maintenance H2 fuel cells?
My understanding is H2 tends to make all storage materials highly brittle over time. This tendency is not favorable for any aviation application.
Still it needs to be addressed. ... 2
@

@AClark-gs5gl3 years ago I've been working on a design for a EDFJ (Electric Ducted Fan Jet), that implements existing ideas for initial use on GA/experimental aircraft. />I'm confident that I can add an additional 30 to 45+ minutes to the current "1 hour" average flight time, using current battery technology.
Also, will allow to travel longer distances, even if only 1 hour, due to higher straight and level cruise speeds.
We shall see, once first tested on Rutan Long EZ and eventually a Velocity 4-place, which will require 2 of my EDFJ power plants and if weight/balance allows, will be mounted on the Velocity aircraft, much like the Honda Jet's.
Until charging stations become common place or aircraft are equipped to allow fast charging via your everyday outlet plug, a hybrid will also be in the works. ... 1

@Acheiropoietos3 years ago THINGS WILL CHANGE (Gorko's Tomb) It's funny reading comments saying this will never take off, etc. We learned to fly in the 20th Century and then landed on the Moon 60 years later.

@shmutube3 years ago So... This relies on much greater cooling efficiency...not the new solidified hydrogen plate (liberated by lasers) tech. Ok got it.

@dejayrezme86173 years ago Very interesting, thanks!
I've been dreaming of building a solar powered cruising boat for a while. It's a much simpler use case with batteries than airplanes of course since payload can be much higher and you don't crash immediately without power. Still it is expensive.
These fuel cells would be really interesting because then you can store large amounts of energy as hydrogen by converting seawater into stored energy.
Thing is to go slow trawler speeds (6-8 knots) you only need 20 kilowatts if you design the boat light enough.
Best examples of this are the Energy Observer and Planetsolar but they are huge gigantic boats. I only want a smaller boat for living aboard and cruising the world. ... 1

@esmenhamaire63983 years ago There's been a bit of a breakthrough recently, I gather, in production of hydrogen from electrolysis. Perhaps one day fuel cells will usehydrogen produced by electrolysis using electricty produced by solar or windpower, for those cases where fuel cells are a more appropriate solution than batteries. ... 10

@

@brookestephen3 years ago What about Seebeck generators to help with the excess heat of the fuel cell? You can turn that waste heat back to electricity for storage in the battery. 4
@

@auspiciouslywild3 years ago I think you’re downplaying the importance of volume in airplanes. With larger planes you can use the wings as fuel tanks. This has several benefits, such as distributing load, not just saving volume for passengers and cargo. With hydrogen you need to put the fuel in separate tanks, taking up valuable cargo space. You can mitigate it with a blended wing body.. but the point is, hydrocarbons will always be superior in any configuration. And if you make them renewably the CO2 is not a problem. Efficiency will probably be even worse, but for many routes it’ll be worth it. So I’m concerned that the niche for hydrogen, squeezed between batteries for short range and biofuel or e-fuel for long range, will just be too small. It’s very possible that more energy dense batteries, and more efficient ways of making and using biofuel/e-fuels, will squeeze hydrogen out of this market. ... 10
@

@dragonrln3 years ago Great video. One key advantage of a hydrogen powered system is the benefit of burning fuel on enhanced range. As the hydrogen is burned, the fuel weight is reduced, with a positive effect on range. This, of course, does not happen with batteries. ...

@dion61462 years ago Methanol fuel cells will eventually outstrip all other contenders. Methanol is high energy density, light weight, and fast filling. They can be coupled with TIDE small turbine running a generator.

@manicsurfing3 years ago toyota banking on hydrogen might have been right.
also looks like bob lazar is correct in storing hydrogen in the form of H1, you'll need a particle accelerator to create 6Li (lithium-6) H (hydride) for H1 storage. ... 1

@glike23 years ago H2 combustion in turbine engines might still have better efficiency vs weight than these turbo fuel cells for large aircraft. Recovering the exhaust heat to pre-heat the fuel may be help the turbine efficiency.

@

@icorezx14r3 years ago I have been starting to wonder why current development on electric vehicles mostly depend on batteries alone or hybrid engine types. Where are the vehicles powered by generators alone with battery back up? Natural gas (or better yet hydrogen) generators could supply most of a vehicles energy needs with batteries to be back up in case of generator failure. Small high output generators could be a great course of R&D while battery development is ongoing. Accelerating electric vehicle production is my goal here, and even if we had to use fossil fuel generators for a while. It could get electrics into the hands of consumers quicker and start the snowball needed for mainstream acceptance. ...
@

@ZephodBeeblebrox3 years ago I have always considered battery powered vehicles to be a massive wrong turn. Look at the experience of the Orkneys. They have surplus wind and solar power they use to crack seawater into hydrogen and oxygen. The hydrogen they compress and use to power conventional engines. Using fuel cells is a fantastic idea but limited by the cost of platinum. ...
@

@abyssalblue30892 years ago I feel like there should be a lighter, far less expensive catalyst besides Platinum. Weren't graphene membranes found to far exceed platinum back in 2004? Just doing a quick search showed multiple advents in fuel cell technology evolution that completely negates the use of Platinum. ...

@6355743 years ago At that price maybe only large crafts designed for range could use it. Such absurd cost is expected If they didnt design it for manufacturing first

@Healitnow3 years ago Talk about hydrogen all you want, but I would buy electric. It has so many charging options and some of them like solar panels do not require paying at the pumps all the time. This allows me more freedom of spending on other things. ...

@mho...3 years ago Im starting to feel like Fuel Cells for Vehicles is like Fusion.... always just some years/decades away 🤓
@

@stevemickler4523 years ago For smaller craft structural Lion would effectively deliver well over half the range at significantly lower cost both for purchase and operating. Simple proven and efficient while fuel cell systems require maintenance and could fail. This means you really need two fuel cell systems for equal safety doesn't it?
Electricity can be made available quickly, cheaply and easily compared to hydrogen. It would make more sense to pay a solar power plant to scrub an amount of CO2 from the air that the equivalent burning of jet fuel would make and not have to buy any new equipment. It would extend the life of the existing stock of planes and put pressure to develop cheaper carbon capture systems which helps way beyond aviation. ...

@NMIBUBBLE3 years ago wow the weigh is kinda high oppose to eplane 1 flight time is 222, eplane 3 is 148 flight time. So if the flight time is better on eplane 1 wouldn't that be the one to go with? Because it beats the rest of them hands down! it's at . ...

I wonder if you could dig up more information about this thing, and about what your opinion about it is. ... 2
@

@Allan_aka_RocKITEman3 years ago IMHO, the ONE big issue for battery electrics versus hydrogen fuel cell electrics is recharge time.
When you can refuel {recharge} the battery is quickly as refueling the hydrogen in a fuel cell powered vehicle, you will be there.
Until then, I will prefer the fuel cell. ...

@tepidtuna74503 years ago While I like the fuel cell concept shown here, it is a single point of failure.
Having a small buffer battery would be ideal for emergency landings and intermittent cutouts.
Better still would be proven use via long term reliability in low-risk non-aviation transport, such as road transport.
However, that is unlikely in this configuration. Promising tech though. ... 1

@

@JohnBoen3 years ago Bored engineer doing a simple feasibility study... how about a 10kwh cell?
Power extraction happens at a rate of about 5 watts per square meter of surface area in platinum based devices.. and this is at high pressure. If you want to pull a constant 10kwh, you need 2000 square meters of platinum surface.
And if you electroplate aluminum foil to 0.01 mm with platinum, you need 20 cubic cm of platinum for this device. About one pound... $14,000.
Assume you can align all the plates so you get two per mm. 2000 square meters at 0.5 mm thick. 1 cubic meter of reactive surfaces, and whatever for housing, pumps, etc... if it's mostly aluminum, I assume about 500kg. However, foils tend not to work well in hurricane winds... I don't see an immediate solution thst would give 200 sq meters...
Typical fuel cells are 40-60 percent efficient, and 1 kg of hydrogen with its 33.6 kwh would last a little under 2 hours. Ignore fuel mass for now.
10kwh/500kg - otherwise known as 200 wh/kg. This is today's typical lithium ion power density.
I expect it will take 5-10 years to develop this technology into a commercial product.
What do you think power density of Li Ion will be in 5-10 years?
I think we will have 450 wh/kg solid state batteries by that time.
A cool technology, but they are not telling the whole story. ...

@matthewjacobs1413 years ago I can see a time when homes are fueled through natural gas fuel cells...no more blackouts because the powerlines were taken down by falling trees...more power to use because there will be no loss due to resistance loss in high power lines moving Electricity hundreds of miles...A home fuel cell will not only produce power on demand but will provide hot water to the home ... 1

@bencowles21053 years ago interesting. too bad the aviation designs they are using are so inefficient.
@

@coreyfro3 years ago You still grossly overestimate the performance of batteries in these comparisons. For example, you ignore the fact that fuel cell craft get lighter as fuel is consumed. This vastly extends the range of the vehicle. Battery craft do not have this advantage. Also, every time you mention the start up cost of a fuel cell, you suggest that an onboard battery is required. It isn't. This power, for certain limited load applications, can be provided by shore power. Thus, the onboard intermediate battery can be reduced or completely removed. ... 1
