| 摘 要： | 根据氢-空气燃料电池系统组成,建立了燃料电池系统数学模型。通过模型计算得出环境条件、电堆温度、空气流量参数对系统效率的影响关系。计算结果表明,除了在高温或高湿条件下,环境条件的改变对系统效率的影响较小;高温或高湿条件有降低系统效率的趋势。电堆温度对燃料电池系统的效率有显著影响。温度从30℃升高到80℃时,系统效率逐渐增加。低负载时,空气流量对系统效率的影响比较显著。流量增大时,系统效率下降,流量超过30SLPS时,效率下降接近于零。

| Abstract: | A numerical modeling of a hydrogen/air PEM fuel cell system was built.The effects of operating conditions and air flow parameters on the system efficiency were calculated and simulated based on the numerical model.These conditions included various ambient temperature,relative humidity,various stack temperatures and minimum mass flow operation.The changes in ambient conditions had a small effect on the system efficiency except hot and humid conditions,which tended to lower the system efficiency.The stack tem... |
