Low Power Metal Hydride Fuel Cell/Battery Hybrid Systems

Abstract

The use of solid hydrides, solid super-oxides and hydrogen peroxide are examined as possible reactant sources for small fuel cell systems. Life testing of small calcium hydride-hydrogen peroxide powered alkaline matrix fuel cell is described. A complete six volt fuel cell subsystem was constructed using calcium hydride as fuel and hydrogen peroxide as oxidant. Water vapor produced by the fuel cell is used to react with the hydride to produce further hydrogen fuel. A Kipp Generator supplies oxygen from the catalytic decomposition of the hydrogen peroxide. The six volt output from the fuel cell is fed into a DC-DC converter where its output is boosted to 32V. The 32V is floated across 23 - 50mA hour nickel-cadmium batteries. The total system can deliver a steady 2mA at 32V or 430 mA-60ms pulses at 26V.
