ABSTRACT:
A power generator has a hydrogen producing fuel and a fuel cell having a proton exchange membrane separating the hydrogen producing fuel from ambient. A valve is disposed between the fuel cell and ambient such that water is controllably prevented from entering or leaving the fuel cell by actuation of the valve. In one embodiment, multiple fuel cells are arranged in a circle around the fuel, and the valve is a rotatable ring shaped gate valve having multiple openings corresponding to the fuel cells.
