ABSTRACT:
A battery capable of extended operation at high temperature includes a cell of laminated construction utilizing a solid oxidant cathode, an electrolyte element, a catalyst and a gas impermeable separator sheet providing an anode for the cell, with each element in electrical connection with the next. The solid oxidant is a mixture including powdered manganese dioxide, carbon and caustic material, the electrolyte element is a mixture including powdered magnesium oxide, and a binder, pressed into a solid pellet and soaked with caustic material. The cell further has a porous carbon paper substrate in electrical contact with the gas impermeable separator sheet and the catalyst is platinum dispersed on and adhered to the substrate. A source of hydrogen gas is provided, and when the battery is exposed to the hydrogen gas, a voltage is generated.
