When wouldn't it be at a loss? That's just physics. Hydrogen fuel cells aren't a source of energy in and of themselves, they're just a storage medium, like any other battery. And the act of filling them will never by 100% efficient because nothing is, so there will always be loss.
- FabHK 6y agoYes, any conversion incurs a loss. The point is that hydrogen introduces additional conversions, because it must first be produced, and then converted to something useful.
- polishdude20 6y agoHydrogen fuel cells don't store the hydrogen. They convert the hydrogen into electricity. The losses come from a: converting electricity to hydrogen by electrolysis and b: converting that hydrogen back to electricity.
