Fuel cells producing *liquid* water?
Robert Clark wrote: I meant using cryogenic liquid hydrogen would make it easy to liquify the water. As noted by Cowan, 4 bar might be too high for a lightweight system. I got this number from high performance fuel cells. They would work at 1 bar just not as efficiently. Er, Bob, just how big is the H2 tank going to be?
