Abstract
A performance enhancing break-in method for a proton exchange membrane ('PEM') fuel cell () includes cycling potentials of an anode electrode () and a cathode electrode () from a first potential to a second potential and back to the first potential, and repeating the cycling for each electrode () for at least two electrode cycles. The potential cycling may be achieved in a first embodiment by applying a direct current from a programmable direct current power source () to the electrodes. Alternatively the potential cycling may be achieved by varying reactants to which the anode and cathode electrodes () are exposed.
