大功率燃料电池运行条件的研究

Investigation on the optional operating conditions for high power PEM fuel cell

采用正交法设计实验,利用不同结构的流场组装的两台50kW质子交换膜燃料电池堆运行,探索各种电池运行因素(温度、相对湿度、反应气利用率等)对大功率燃料电池堆稳定运行的影响,获得较优的燃料电池运行条件;为大功率燃料电池发动机的稳定运行提供参考。

The studying on the characteristics of two 50 kW PEM fuel cell stacks with different flow fields at high power output was conducted. The influences of various operating conditions (temperature, RH, utilization of reacting gas and etc.) on running stability of fuel cell stacks have been tested by orthogonal test method. The optional operating conditions are obtained which is available reference for running of fuel cell engine with high power.
