Water can also be reclaimed from lithium hydroxide scrubbers.

anonymous · Answer

so from fuel cell

anonymous · Answer

The common hydrogen fuel cell oxidizes hydrogen to produce electricity and water.
2H2 + O2 --> 2H2O.

The lithium hydroxide scrubber (removes carbon dioxide from the air) also produces water in a hydride form:

2LiOH + CO2 --> Li2CO3.H2O

The hydrate water can be boiled off and then condensed back to liquid.
