  • Fuel cell system having a replaceable getter element for purifying the fuel supply
    Patent number: 6689194
    Abstract: Oxides of carbon and other impurities are removed from a hydrogen fuel supply stream (12) for a fuel cell (30). A getter element (20) sufficient for chemisorbing the oxides of carbon from the hydrogen is removably connected to the fuel cell anode side. The fuel stream is passed through the getter element so as to chemisorb the oxides of carbon onto the getter, thereby providing a purified stream of hydrogen (26) to the fuel cell anode. The getter is removed from the fuel cell when the getter is spent and replaced with a fresh getter.
