液相进料直接甲醇燃料电池性能的实验研究

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。图8参7

Experimental Study of the Performance of Liquid Fed Direct Methanol Fuel Cells

Performance of liquid fed direct methanol fuel cells have been experimentally studied by using(U.S.) Arbin Co.'s fuel cell testing system(FCTS).Effects of parameters on the performance like working temperature and pressure,pressure differential across anode and cathode,flow rate of methanol and oxygen,concentration of methanol,have all been studied via electric current-voltage curves.Experimental results indicate that the cell's performance improves with rising fuel cell temperature and drops with increasing pressure differential across anode and cathode;the fuel cell's performance improves more or less with the working medium's increasing rate of flow and concentration as well as with the cell's rising working pressure in case the methanol's concentration is relatively low.Figs 8 and refs 7.
