减少燃料电池退化的方法
摘要：
本发明是减少膜电极组件燃料电池的阴极中催化剂溶解的方法，所述方法包括以下步骤：(a)制备膜电极组件，该组件包括阳极、阴极和位于所述阳极与所述阴极之间的聚合物电解质膜；(b)使用所述膜电极组件组装燃料电池；(c)向所述膜电极组件的所述阴极提供包含氧化剂的流体；(d)向所述膜电极组件的所述阳极提供包含燃料的流体；(e)向所述阴极提供足量的还原剂，以将所述阴极的平均开路电压保持在小于约0.98伏。
摘要（英）：

The invention is a method of reducing catalyst dissolution in the cathode of a membrane electrode assembly fuel cell, the method comprising the steps of: (a) preparing a membrane electrode assembly comprising an anode, a cathode and a polymer electrolyte membrane interposed between the anode and the cathode; (b) assembling a fuel cell using the membrane electrode assembly; (c) applying a fluid comprising an oxidant to the cathode of the_membrane electrode assembly; (d) applying a fluid comprising a fuel to the anode of the membrane electrode assembly; and (e) supplying a sufficient quantity of reducing agent to the cathode to maintain the average open-circuit voltage of the cathode at less than about 0.98 V.
