Wikipedia says that in practice, fuel cells are 40-60% energy efficient, compared to 25% for a typical internal combustion engine.

https://en.wikipedia.org/wiki/Fuel_cell#Theoretical_maximum_...

Comparing tank-to-wheel efficiency of the whole vehicle, fuel-cell vehicles average 36%, compared to 22% for diesel.

Could you explain how you got the 10% / 20% efficiency numbers you mentioned? Your combustion numbers are in the same ballpark, but you got a much different result for fuel cells.

Genuinely curious, thanks!

It's worth pointing out that those numbers are of _ideal_ RPM and ideal power draw, real world results will vary significantly.
