According to the experimental results, both the conducting area and material of current collector slices have great influence on the performance of micro PEMFC, especially the former one. The increment of cell's performance is finite by increasing the gas reheats temperature. The performance is better for open ratio 75% compared with 50% and 67%. The concentration polarization is improved by increasing the air flow rate at high current density and if the GDL diffusive capability in the latter cell could be promoted, the differences between these two cells' performances would be reduced.
由实验结果可知,集电片的导电面积与材料对於电池性能有显著的影响,尤其是前者;对於增加反应气体的再热温度,微型燃料电池增加的性能有限;双极板开孔率75%相较於开孔率为50%与67%有最佳的性能曲线;增加阴极气体空气的流量,可以改善高电流情况下的浓度极化现象,所以若我们能增加气体扩散层的扩散能力,则可以减少两者的性能差距。
