Why This Hydrogen Fuel Cell is Engineering Genius

Hydrogen fuel cells are a fantastic way to generate electricity from energy dense hydrogen, that can be produces using renewable energy. This means they are a great option for low carbon transportation, especially as the distances get longer! However, aviation has always been a challenge. Thankfully, ZeroAvia have been working on an amazing new technology: turbo charged air cooled high-temperature pem fuel cells. These have much higher power densities and therefore enable long distance hydrogen electric flight. I went to their labs to check it out!

This breakthrough is what happens when engineers look at a problem at a system level! Amazing work. Also, don't forget to check out the interactive courses from Brilliant! Use my link at brilliant.org/ziroth/ for 30 days FREE and 20% off a subscription!

Pro tip: don't put "insane" in your header. In 2024, it means "mediocre clickbait".
-
Again "slapping a turbo on it" was the solution.

This company seems primarily focused on the efficiency in the functioning of the fuel cell itself rather than one of the biggest problems of this application. In order to really compete on distance, you need liquid hydrogen. Liquid hydrogen is stored at -253° C and that presents some serious problems for a plane
-
While not taking anything away from this work no actual data of thermodynamic efficiency was presented, additionally the current cost of both fuel cells and electrolisers are very high. Producing hydrogen is always going to be very expensive. More energy must go in to produce the hydrogen than ca be extracted (therodynamics). A lot different to drilling a hole in the ground and getting oil out.

This is a GREAT introductory explanation of fuel cells. Thanks.

"If there were no challenges, it would be done already." 20:08 I just loved the phrase
-
Haven't high temp fuel cells always been more efficient? That was the big issue in fuel cell development early on. You could get plenty of reliability and power from a high temperature fuel cell, but your car had to heat up to work properly. Also, power from fuel cells has never been the issue. It's always been that hydrogen is slippery. It can leak out of most fittings and can even squeeze in between molecules of solid objects.
-
When the thumbnail says, "+350% power!", it might as well be one bajillion kajillion power! You mean, more than a Tardigrade? Awful.
-
It does not matter how well any hydrogen system operates. The massive problem hydrogen has is its production storage and distribution. Considering is propensity to permiate just about any material these are massive.
-
No mention of hydrogen storage? How much bleed off is there? Is the tank in an aircraft somewhere in the fuselage? The tech sounds good but there is always the problem of keeping the fuel at super low temperatures.
-
thank you for sharing these awesome ideas and inventions, having an interest for renewable and clean energy, it is great to see so many new ideas popping up
-
Another awesome video - super cool to have the interviews :)
-
Great review, thanks. Looks like the way to go..
-
Hey @ZirothTech first time viewer but someone with decades of experience in aviation and covering clean / renewable energy. You did a fine job on a very complicated subject. Well done. Appreciated how you established that while not a widely commercialized technology, PEM fuel cells have been an operational technology in specific applications for a very long time.

FYI: Alaska Airlines is NOT a "regional" airline. It flies internationally. Not a complaint, just a correction.

16:20 I wish I had a movie production right now in which I could propose to Rudolf for him to play a role in it. He has an incredible screen presence, IMO. The potential I see in him is off the charts. If I had the skills to manage my way out of a paper bag, I'd offer to be his manager in the movie business!
-
Well, although that company is based in the USA, I'd have to say that it's about as international a team as you could find anywhere. Looking forward to seeing how they get on.
-
Insane video! Exciting to see Zero Avia from the inside! The picture of the Boeing 787 at the beginning is misleading though as no one is expecting that size/range anytime soon. An A320/737 would have been more appropriate but a Dash-8 probably the most honest airplane to show at that point
-
Incredible, thank's so much for the excellent video, the content alone is incredibly informative and valuable but your narration, editing and videography skills are fantastic. It would be so cool to see this technology applied for marine applications as well, the heat is incredibly useful for things like heating living quarters, water makers, and generators because the power to weight ratios are less demanding in such an application space.
