You have to recognize that converting water vapor to liquid consumes

Wow, you got that completely backwards.


Not really.

Some of the extracted fuel cell energy is in the form of latent heat
that created the gaseous state.

If you cool to liquid water by removing heat and throwing it away in a
radiator or whatever, that energy is gone and not available for the
useful intended application.

Thus, the fuel cell efficiency goes DOWN unless you do something useful
with the latent heat extraction. The low delta-T and Carnot guarantees
useful extraction will be inefficient and enormously difficult.

But the whole project makes no sense whatsoever.
