摘　　要：对自制的阴极开放式自增湿型质子交换膜燃料电池(PEMFC)系统对外输出功率、平均工作温度及阴极风扇系统寄生功率影响开展了实验研究。实验结果表明:阴极风扇系统寄生功率与PEMFC系统对外输出功率之间存在紧密的关系。当阴极风扇系统寄生功率逐渐增大,PEMFC系统的平均工作温度呈逐渐下降趋势,而输出性能则逐渐上升。PEMFC系统输出性能的极值点不等于其平均工作温度的极值点,二者之间并非呈现单纯的线性关系,且存在最佳工作温度。The experiments about the output power, parasitic power influence and the average temperature of a home-made PEMFC stack with open-cathode and self-humidifying running in different experimental methods were researched. It was observed that there was a close relationship between cathode fan system parasitic power and output power of PEMFC system. When fan system parasitic power was gradually increasing, the average temperature of PEMFC system was decreased,output power was gradually increasing. Extremum point of PEMFC system output power was not equal to extremum point of average temperature,output power was not simple linearly related with the average temperature,there was an optimum operating temperature.
