Abstract
A power generator comprises a hydrogen producing fuel, multiple fuel cells arranged in a ring, and a rotatable ring valve. Each fuel cell has a proton exchange membrane and an opening separating the hydrogen producing fuel from ambient. The rotatable ring valve has multiple openings corresponding to the openings of the fuels cells such that ambient water is controllably prevented from entering the fuel cell by rotation of the ring valve.
