A method of fuelling an intermediate-temperature solid oxide fuel cell co mprising the steps of providing (11b) a fuel rich in carbon monoxide to the anode region (10d) of the fuel cell, after the fuel has contacted a water ga s shift reaction catalyst (10bl, 10b2) in the region of the anode, so that t he water gas shift reaction occrus due to the presence of residual water in the fuel, and/or steam produced at the anode, and also a fuel cell assembly incorporating the method comprising an anode (10d), a cathode 10f separated from said anode, a gas impermeable electrolyte (10e) between said anode and said cathode, first means for the supply of oxidant to the cathode lie, seco nd means lib for the supply of fuel to the anode, wherein said second means comprises a water gas shift reaction catalyst (10bl, 10b2) disposed closed t o the anode to catalyse the water gas shift reaction between carbon monoxide in said fuel and water/steam occurring as a residual in said fuel or from t he reaction at the anode. There is also a method of applying a catalyst to a metal substrate by ink- jet printing |
