中文摘要:在三维、两相、非等温模型的基础上,分析了阴极参考体积交换电流密度和阴极传递系数对电池内传递过程(包括气体传递特性、局部电流密度及膜中水传递)的影响。分析结果表明,随着阴极参考体积交换电流密度和阴极传递系数的增加,电池性能不断提高;低电压时,阴极参考体积交换电流密度或阴极传递系数的增加,均可改善电池的气体传递特性及局部电流密度分布。阴极参考体积交换电流密度或阴极传递系数的增加,使膜中含水量的分布不再均匀。
外文摘要:Based on three-dimensional,two-phase,non-isothermal proton exchange membrane fuel cell(PEMFC) model,the paper analyzed the effect of cathode reference exchange current density and cathode transfer coefficient on the transfer process of PEMFC.The results show that:With the increase of cathode reference exchange current density and cathode transfer coefficient,the battery performance was improved;on the condition of low voltage,increasing cathode reference exchange current density or cathode transfer coefficient would improve the battery's gas transmission characteristics and local current density distribution.When cathode reference exchange current density or cathode transfer coefficient increases,it would make the membrane water content distribution uniformly.
