摘要
Abstract
The performance degradation law of a fuel cell system for stationary power plant under constant load was investigated.The voltage and power of fuel cell system decreased linearly over time,the stack and cell's voltage decreasing rate was 0.042 V/h,0.37 mV/h,respectively,the stack and auxiliary system power's decreasing rate was 2.8 W/h and 0.4 W/h,respectively.Both the stability of fuel cell stack and the uniformity of cells dropped during 150 h working,the efficiency of fuel cell system decreased by 3％.The stack performance was limited by the worst cell,the auxiliary system power was a main factor of the system efficiency.关键词
