阳极气体杂质对PEM燃料电池性能的影响

Effects of fuel contaminations in anode on the performance of proton exchange membrane fuel cell

气体中的杂质对燃料电池的毒化影响是阻碍质子交换膜燃料电池(PEMFC)商业化的主要原因之一。综述了阳极气体杂质(CO、CO2、H2S、NH3和各种碳氢化合物)对电池性能的影响,并进行了比较。研究表明,杂质对电池的影响与杂质浓度、电池温度、电流密度、毒化时间以及气体压力等因素有关。

The poison effect of contamination is one of the main factors that impede the large-scaled commercialization of proton exchange membrane fuel cell （PEMFC）. The effects of fuel contaminations in anode （CO, CO2, H2S, NH3 and carbon-hydrogen compounds） on the performance of proton exchange membrane fuel cell （PEMFC） were presented and compared in this paper. It was found that the degree of poisoning was relate to the impurity concentration, the cell temperature, the current density, the poison duration and the gas pressure.
