摘要
组装二氧化硫-空气质子交换膜燃料电池,探讨水流速度、SO_2气体流速和流向等因素对二氧化硫-空气质子交换膜燃料电池电流和稳定开路电压的影响。实验结果表明,SO_2气流方向从下而上,水流方向从上而下为最佳;在单电池的电极面积为5 cm^2时,水流速度和气流分别为1.0,40 mL·min^(-1),电池的稳定开路电压和电流分别为220 mV和16.25 mA,达到最大值。
A PEMFC was assembled, and key factors influencing its performance were investigated concerning the flow rates and the flow directions of water and SO, involved. The results showed that the optimized flowing directions of SO2 and water are down-to-up and up-to-down, respectively. When the single cell electrode area is 5 cm2, and the respective flow rates of water and SO2 are 1.0, 40 mL ·min^-1.Its most stable open voltage and current is 220 mV and 16.25 mA, respectively.
