【摘要】 利用美国Arbin公司燃料电池测试装置,对液相进料直接甲醇燃料电池的性能进行了实验研究。通过电流——电压曲线,研究了燃料电池工作温度和压力、阴阳极差压、甲醇和氧气流量、甲醇浓度等参数对电池性能的影响。实验结果表明,较高的电池温度,可以提高电池的性能;阴阳极差压提高,电池性能降低;在甲醇浓度较低时,燃料电池工作压力、工质流量和浓度的增加均使燃料电池性能有不同程度的提高。更多还原

【Abstract】 The performance of the liquid feed direct methanol fuel cell was studied with Arbin fuel cell test system (FCTS) under various cell temperature, operation pressure, differential pressure between cathode and anode, liquid methanol and oxygen gas flow rates, and methanol concentration. The experimental results indicated that the performance of DMFC increases as the cell temperature increasing, but with the increase of differential pressure between cathode and anode, the performance of DMFC reduces. Under lower methanol concentration, a higher operation pressure, larger liquid methanol and oxygen gas flow rates, and higher methanol concentration lead to a higher performance of DMFC.更多还原
