杂质气体对质子交换膜燃料电池性能影响的研究进展
Research progress of effect of impurities on PEMFC performance
摘要
Abstract
Commercialization of polymer electrolyte membrane (PEM) fuel cells is seriously restricted by its poor durability. Trace amounts of CO,CO2,H2S and NH3 in fuel gas and pollutants,such as NOx,SOx in air are the main factors which affect the durability of PEMFC. The influence and mechanism of fuel gas impurities and pollutants in air on the performance of PEMFC are reviewed. The CO in fuel gas can influence not only anode performance of PEMFC , but also cathode performance through diffusion and mass transfer. H2S can not only cause serious influence on anode performance,but also obviously damage cathode performance of PEMFC. NOx in air can significantly affect the performance of PEMFC,but this process is reversible. Finally,the research on the effect of impurity gases on the durability of the PEMFC needs to combine computer modeling with experiment tests. In addition,it is necessary to study the effect of impurities on the performance of PEMFC stack.关键词
