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!
