摘要 质子交换膜燃料电池(PEMFC)工作参数的影响最终要体现在对电池内传质过程的影响上。实验得到了在不同进气加湿程度下电池性能在启动工况中的变化,基于非稳态数学模型计算了不同阴极入口湿度下电池在负载渐变工况下膜内含水量和电流密度的瞬态响应,并与相应的实验工况进行了对比。 Performance of the proton exchange membrane fuel cell (PEMFC) under various operating conditions is reflected in the internal mass transport process. Effects of different inlet humidity on PEMFC performance during a simulated start-up process have been explored experimentally. Based on a three-dimensional transient model the effects of membrane water content and current density on the cell dynamic performance during load gradual change are investigated and compared with the experimental data.
