| 摘 要： | 利用MEMS技术设计并制作了有效面积为1.2cm×1.2cm的不同阳极和阴极结构,将它们组成电池并进行比较。结果表明,阳极采用点-蛇形混合流场,电池峰值功率密度为比点状流场的电池可提高10.4%;阴极采用双层镂空流场,峰值功率密度比单层镂空流场电池增加15.7%。最优结构电池在30%～50%相对湿度下性能良好,200mA恒流放电近610h,电池电压比较稳定。

| Abstract: | Different anodes and cathodes with active area 1.2 cm×1.2 cm were designed and fabricated using microelectromechanical system(MEMS)technology,and assembled for air-breathing micro proton exchange membrane fuel cells(μPEMFC).The results indicated that the peak power density(P_ max)of fuel cells with pin-serpentine-combined anode flew field is 10.4% higher than those with pin anode structures.The P_ max of fuel cell with a cathode flew field of two layers with small channels is 15.7% higher than that with a single layer cathode structure.The fuel cell with the best cathode and anode structure gives excellent performance at 30%～50% RH,and the cell voltage is steady at a discharge current of 200 mA lasting for 610 h. |
