摘要
质子交换膜燃料电池的流道及扩散层对均匀化氧的分布起着非常重要的作用 .模拟分析的结果表明增大流道深度有利于氧在扩散层表面的均匀化分布 。
The channel and gas diffusion layer play an important role in making oxygen even distribution, the result of simulation and optimization shows that when the width of the channel is unchangeable, the more the depth of the channels are, the evener the oxygen on the surface of diffusion layer becomes. The even degree going through the diffusion layer depends on relative change of diffusion resistance in crosswise and lengthways. If the diffusion resistance in crosswise is bigger, it will not benefit the oxygen distribution.
