Fuel-cell plant for autonomous power supply

Abstract The construction and testing of an operating model of a 7 kW hydrazine oxygen fuel cell plant is described. The oxygen is obtained by catalytic decomposition of hydrogen peroxide immediately prior to use. The maximum output of the plant is 11·2 kW (100 A, 112 V). An electronic system controls starting, automatic operation and shut-down. Starting takes 1–2 min. The overall efficiency of the entire plant—referred to the hydrazine—is 0·51.
