An SPE Static Water Vapor Feed Electrolyzer has been developed, under contract to NASA/JSC, as a candidate for Space Station life support oxygen generation. The fivecell electrolysis module has eliminated the need for separation decices, pumps and deionizers by transporting only water vapor to the solid polymer electrolyte cells. The introduction of an innovative electrochemical hydrogen pump allows the use of low pressure, reclaimed water to generate gas pressures of up to 230 psia. The electrolyzer has been tested in a computer controlled test stand featuring continuous, cyclic and standby operation including automatic shutdown with fault detection.
