摘要
根据伏安曲线分析了质子交换膜燃料电池(PEMFC)的电极热源项和能量损耗比例。研究了PEMFC的电极过程特性以及对电池能量转化效率和热源的影响。在标准状态下,电池以0.60 V的电压工作时,实际能量效率为40.5%。
Heat sources of the electrode and their proportion of the energy wastage in PEMFC were analyzed by the vohammetry curves. The characteristics of the electrode process and its effects on energy transfer efficiency and the heat sources of PEMFC were studied. At normal status, the actual energy efficiency was 40.5% under the voltage of 0.60 V.
