| 摘 要： | 全面研究了PBI/H3PO4体系高温质子交换膜燃料电池(PEMFC)的操作性能,研究了温度、压力、阴极气体成分(空气/氧气)对电池稳态操作性能的影响,同时,测试了电池的变压变温和变负载操作曲线,并且运用电化学交流阻抗谱的方法解释了操作条件对电池性能影响的原因,同时应用薄膜旋转圆盘电极技术初步研究了氧还原反应在两种不同的反应界面(Pt/C-PBI/H3PO4和Pt/C-Nafion/H2SO4)的差别。

| Abstract: | The operational performance of PBI/H3PO4 high temperature PEMFC was studied systematically, the effect of operational temperature, pressure and cathode gas (O2 or air) were studied, and the dynamic performances for different temperatures, pressures and loads were measured. Electrochemical Impedance Spectroscopy (EIS) technique was used here to interpret the reason for the effect of operational parameters (cathode gas) on cell performance. Thin film electrode technique was used here to study the difference of the oxygen reduction reaction (ORR) on two reaction interfaces (Pt/C-PBI/H3PO4 and Pt/C-Nafion/H2SO4). |
