摘要：
A fuel cell includes an anode layer, a polymeric ion conductive membrane disposed over the anode layer, a cathode layer disposed over the polymeric ion conductive membrane, and an effective amount of a reactive material that corrodes at a higher rate than support carbon in the cathode layer, anode layer, or both. The reactive material is either proximate to or distributed within the cathode catalyst layer. In a variation, reactive material is also included proximate to the anode layer.
