摘要
建立燃料电池的电压模型,预测性能随温度和背压的变化趋势。测量质子交换膜燃料电池(PEMFC)的电流密度-电压、电流密度-功率密度,验证操作参数对PEMFC性能的影响。在背压为0.2MPa、温度为70℃的实验条件下,PEMFC的性能最好;超过适宜的温度范围(60~80℃),性能显著下降。对流场进行电镀处理,PEMFC的性能可提升29.18%。
The trend of performance with temperature and back pressure was predicted by establishing a fuel cell voltage model.The current density-voltage,current density-power density of proton exchange membrane fuel cell(PEMFC)was measured,the effect of operating parameters on the performance of PEMFC was analyzed.Under the experiment conditions(back pressure of 0.2 MPa and temperature of 70℃),the performance of PEMFC was the best,exceeding the suitable temperature range(60-80℃),the performance decreased significantly.By electroplating the flow field,the performance of PEMFC was improved by 29.18%.
