1kW熔融碳酸盐燃料电池 (MCFC)组由有效电极面积为 2 4 0mm× 140mm的 30个单电池组成 .系统采用内部分配方式供给气体 ,通过设在电池组底部和四个侧面的电炉丝进行加热 .在常压和 65 0℃条件下 ,分别以氢气和空气作燃料和氧化剂 ,放电电流密度为 15 0mA/cm2 时 ,平均每电池的输出电压达到 0 .7V .在运行的 30 0h内 ,电池组峰值输出功率达到 1.0 6kW .

A molten carbonate fuel cell stack with an active area of 240 mm×140 mm consisted of 30 cells.The gas feed system works via interior manifolds,and the stack placed in a couple of self-chest,coupled with a heater at the bottom and other fours surrounded,to keep uniformity of temperature.Under ambient pressure and 650 ℃,fed with hydrogen and air as anode and cathode gases respectively,the stack gave a current density of 150 mA/cm 2 at an average cell voltage of 0.7 V.The peak output of the stack was 1.06 kW during its performance of 300 h.
