质子交换膜燃料电池的研究

Study of Proton exchange Membrane Fuel Cells(PEMFC)

通过测定电压～电流密度曲线等方法研究质子交换膜燃料电池的电极参数，构造了Ｅｃｅｌ＝０．７Ｖ，Ｉ＝０．５５Ａ／ｃｍ２并能够稳定运行的燃料电池．改进电池的电极结构，研究了各种操作条件如温度、压力、增湿情况、尾气流量等对电池性能的影响．

The electrode kinetic parameters for proton exchange membrane fuel cells(PEMFC) were investigated by measuring the relations of cell potential and current density. An experimental stack of PEMFC which can be operated at E cell =0.7V, I =0.55A/cm 2 steadily is presented, and the effects of electrode structure and operation conditions such as temperature, pressure, humidification, flow rate on the performance of PEMFC are discussed.
