Default Fuel cells producing *liquid* water?

You have to recognize that converting water vapor to liquid consumes
energy and has to be charged against the fuel cell efficiency budget.


Wow, you got that completely backwards.

Water vapor gives up energy when it condenses to liquid. You could
harvest additional energy from the steam as it cools back to room
temperature.

Batteries are almost certainly more cost effective.
