摘要： 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.

摘要： An apparatus and method for humidifying a fuel cell flows moisture-containing fuel cell exhaust against a first side of a humidification membrane. A second side of the humidification membrane is in physical contact with the inlet air flow. Moisture from the exhaust air is transferred across the humidification membrane to the inlet air flow. The humidified inlet air flow conveys moisture to the power section of the fuel cell. In this manner, fuel cell components requiring humidification, for example a proton exchange membrane, are prevented from becoming dehydrated and inoperable.
