Low Wattage Hydrogen - Air Fuel Cells
Abstract
Low Wattage fuel cells based on the matrix type phosphoric acid cell are discussed. Nominal ratings of 5-watts or less are considered. Bottled hydrogen or metal hydrides are used as fuel. Two approaches are taken. One relying on a conventional bipolar cell design with water removal by the air stream. In an alternate approach, metal hydrides are integrated with the fuel cell into a device resembling a primary battery. Hydrogen is generated by reaction of the hydride fuel with the fuel cell product water. Power sources based on the phosphoric acid cell exhibit favorable life characteristics and power densities comparable to or exceeding low rate primary batteries.
