    Abstract: A low temperature proton exchange membrane fuel cell (PEMFC) system can be efficiently started even when the system is at a temperature near or below freezing (0° C). The cold start procedure is accomplished through heating the fuel cell by filling an anode chamber with fuel (hydrogen or hydrogen-rich reactant gas) and generating hydrogen on a cathode. A defined amount of oxygen is supplied to the cathode chamber. The fuel cell system is locally heated up to defined temperature by the exothermic chemical reaction between hydrogen and oxygen on a cathode catalyst. Then the hydrogen generation on the cathode is canceled and oxygen is supplied to the cathode chamber in an amount sufficient to maintain the current flowing through an external load. This procedure provides plain saturation of the cathode with hydrogen and, as result, mild, safe and fast heating the fuel cell without use of additional external devices.

    Abstract: A low temperature PEM fuel cell system is prevented against freezing after a shutdown in sub-freezing conditions. The fuel cell can be heated by filling an anode chamber with a fuel (the hydrogen or a hydrogen-rich reactant gas) and generating the hydrogen on a cathode. A defined amount of air is supplied to the cathode chamber. The fuel cell is locally heated to a defined temperature by the exothermic chemical reaction between the hydrogen and the oxygen on a cathode catalyst. Once the fuel cell is warmed to the defined temperature, the hydrogen generation on the cathode and the air supply can be discontinued. Water formed at the cathode can be evaporated by means of pre-heating of an air flow. This procedure provides plain saturation of the cathode with the hydrogen and, as result, mild, safe heating the fuel cell without use of an additional external power supply.
