A fuel cell stack is operating on the International Space st

A fuel cell stack is operating on the International Space station. If it is operating at an average cell potential of 0.65V and 30 kW of power, at what rate will it produce water as a product?

Solution

100w fuel cell running at full capacity, would produce about 200ml of water in 12 hours

30kw fuel cell will produce water at (30000*200)/(100*12) ml per hr

=5 litres per hour
