直接甲醇燃料电池中甲醇穿透对电池性能的影响

The effluence of methanol crossover on the performance of DMFC

根据已经建立的液体进料直接甲醇燃料电池一维模型讨论甲醇穿透对电池性能的影响。结果表明:电流密度较低时,甲醇穿透对电池性能的影响较大;随着电流密度增大,甲醇穿透对电池性能的影响越来越小。

Based on the one-dimensional mathematic model,the influence of methanol crossover on the performance of DMFC is discussed in this paper.Simulation results show that the influence of methanol crossover on the performance of DMFC is vital at low current density.With the increasing of the current density,the influence of methanol crossover on the performance of DMFC is less and less important.
