The current density used when charging the fuel cell is between 1 and 10 milliamperes per square centimeter in the PEM fuel cell. The voltage applied to the fuel cell during charging is between 0.5 and 2 volts. AN Independent claim is also included for the following: (a) an arrangement for implementing the inventive method.",
