You’re talking about fuel cells, which are only used with the smallest (prop) design. The two larger jets are intended to have hydrogen turbines, burning hydrogen and producing water. I love the idea of small modular reactors (SMRs) being used to produce the hydrogen from water. We also need a vast buildout of safe, clean, dependable modern nuclear reactors to provide the developing world with enough energy to make the demographic transition (via a higher standard of living) to better environmental practices.
