D109 溶融炭酸塩形燃料電池におけるセル温度分布の改善(ガス流れ方式の検討とスタック試験)

抄録

Molten Carbonate Fuel Cell (MCFC) power generating system is expected to be a high efficient and clean system, and development programs for 1,000kW pilot plant and long life time cell technologies have been finished at Mar. 2000,in the New Sunshine project in Japan. For scale up, it is necessary to eliminate cool and hot spots in a cell, in order to reduce stack temperature distribution, the co-flow type and cross flow type 1kW class stacks with the electrode area of 01.m^2 were developed and tested in development programs for longer life stacks. The measured cell temperature distribution showed good agreement with an analytical results. It was revealed that the co-flow type flow pattern was effective for improvement of cell temperature distribution.
