Abstract

A method of preventing anode oxidation in a fuel cell is disclosed comprising applying a negative current to an anode of said fuel cell, such that the anode is disposed in ionic communication with a cathode through an electrolyte. Oxygen is transferred from the anode through the electrolyte to the cathode. A method preventing anode oxidation in a fuel cell by storing and using a reformate and doping an anode are also disclosed.
