A report proposes the development of a thin-film fuel cell that would generate electric power from two minor constituents of the Martian atmosphere — O2 and CO. These compounds are generated continuously by photolysis of CO2, the major constituent. The fuel cell would include a cathode and an anode made of catalysts suitable for the selective low-temperature electrochemical reduction of O2 and oxidation of CO, respectively. It would also include a hygroscopic gel electrolyte.
