| 摘 要： | 对阴极面为带增湿槽道流场的单电池使用FLUENT软件建立了一个完整的三维数学模型。通过耦合气体控制方程、电化学反应Butler-Volmer方程、膜中水传递方程和水的相变方程,以及分析膜的水含量、阴极催化层水浓度、氧气浓度和膜中电流密度分布;结果表明,最后得到增湿槽道在实现阴极增湿的同时损失了其对应的活性面积。

| Abstract: | A three-dimensional mathematical model of cathode in single cell increased wet channel had been developed with FLUENT software.In this model,the gas governing equation,electrochemistry reactions Butler-Volmer equation,membrane water transport equation and liquid water formation and vaporization equation were solved.By analyzing the membrane water content,cathode catalysis layer water density and oxygen density and distribution of current density in the membrane,we can get the results that the increased wet channel way achieves cathode humidity.And at the same time,it lose its corresponding active area. |
