Development of MCFC and PEFC technologies; Jisedai nenryo denchi no kaihatsu

Abstract

Next-generation fuel cells under development by Toshiba Corporation are outlined. The molten carbonate fuel cell (MCFC) has become stable in performance, which results from the conversion of the matrix group from the {gamma}-type to {alpha}-type LiAlO2. The cathode material is expected to withstand the elution of electrolyte for 20000 hours. The soft structure separator developed for stack constitution is expected to improve electrical contact and reduce the cost of stack. An appliance has been completed to tentatively produce every element concerned. During an actual operation, the structural soundness of the 2-cell stack was confirmed by thermal load tests. As for the polymer electrolyte fuel cell (PEFC), an interior humidification method has been developed using a porous material for supplying water to the polymer film. The amount of moisture can be controlled, which will enable a larger-area cell. A 1kW-class stack with a world-record-level 1200cm{sup 2} electrode area has been developed, which stack has shown that the target output has been attained. Furthermore, the power generation efficiency of the system including fuel treatment has been examined. 10 figs.
