Abstract
Systems that facilitate operating proton exchange membrane (PEM) fuel cells are provided. The systems employ a fuel supply component that supplies fuel to the proton exchange membrane fuel cell; and a regeneration component that provides a reducing agent comprising a mixture of hydrogen and nitrogen, or a reducing plasma to a cathode catalyst of the proton exchange membrane fuel cell to reduce the cathode catalyst.
