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.
