Abstract
A method of fuelling an intermediate-temperature solid oxide fuel cell comprises providing a fuel rich in carbon monoxide to an anode region, after the fuel has contacted a water gas shift reaction catalyst in the region of the anode, so that the water gas shift reaction occurs due to the presence of residual water in the fuel, and/or steam produced at the anode. A fuel cell assembly comprises a gas impermeable electrolyte between an anode and a cathode, first means for the supply of oxidant to the cathode, and second means for the supply of fuel to the anode that comprises a water gas shift reaction catalyst to catalyse the water gas shift reaction between carbon monoxide in the fuel and water/steam occurring as a residual in the fuel or from the reaction at the anode. A method also applies a catalyst to a metal substrate by ink-jet printing.
