介绍了一种以ePTFE为基体、短侧链全氟磺化离聚物为电解质的质子交换膜燃料电池用复合膜。在95°C和40%相对湿度下，以复合膜为电解质的单电池在800mAcm− 2时的输出电压达到0.61V，而以纯短侧链全氟磺化膜为电解质的单电池在相同条件下的输出电压仅为0.41V。在95°C和常压下，对以复合膜为电解质的燃料电池电堆的千瓦级性能进行了实验研究。随着进气温度的升高，电堆的性能得到提高。电池堆中单电池的瞬时平均电压具有非单调性，峰值出现在电池堆温度为90°C时。所观察到的水积聚现象表明，高于90°C时电池堆性能的降低归因于系统中缺乏水。本研究中观察到的结果表明，复合膜具有在95°C下在相对湿度降低至40%下操作的潜力，这是燃料电池车辆应用的合适操作条件。
Composite membranes containing ePTFE matrix and short side chain perfluoronated sulfonated ionomers are introduced as electrolytes for proton exchange membrane fuel cell applications. The output voltage at 800mAcm−2for single cell using composite membrane as electrolyte reaches 0.61V at 95°C under 40% relative humidity whereas it is only 0.41V for cell assembled from pristine short side chain perfluoronated sulfonated membrane at the same condition. The performance of fuel cell stack using composite membrane as electrolyte in kilowatts ranges has been experimentally investigated at 95°C under ambient pressure. With the increase in the inlet gas temperature, the performance of the stack is enhanced. The non-monotonic behavior in instantaneous average voltage of single cells in the stack has been observed and the peak value is appeared at the stack temperature of 90°C. The observed water accumulation phenomena suggest that the decrease in stack performance above 90°C is attributed to the lack of water in the system. The results observed in this study demonstrate that the composite membrane has the potential operating at 95°C under reduced relative humidity to 40%, which is a suitable operating condition for fuel cell vehicle applications.
