概要

Fuji Electric has been developing Polymer Electrolyte Fuel Cells (PEFCs) since 1989. We have evaluated a number of stacks up to 5kW in rated output power and 2000(cm)^2 in electrode area. These experience enabled us to operate under no humidification; dry H_2 and dry air are supplied to the stack which does not include any part to humidify gases. We made this type of H_2-air 1kW class PEFC stack. We will evaluate the automatically controlled city gas fueled 1kW PEFC system at the end of this year, including a stack, fuel processor, heat recovery, inverter, control unit and other components. For stack, in order to operate with the fuel gas including CO, the anode catalyst was changed into anti-CO type and the cell was re-designed to be operated at the elevated temperature of 80℃. 9-cells stack has been operated at 80℃ with the H_2/CO_2=76/24% mixed gas including 10ppm of CO. We also developed the reformer combined CO shift converter, and a CO remover.
