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