A solid oxide fuel cell comprising a solid oxide electrolyte layer, a
cathode layer on a cathode side of the electrolyte layer and an anode
layer on an anode side of the electrolyte layer, and wherein a
hydrocarbon reforming layer is also disposed on the anode side of the
electrolyte layer, said hydrocarbon reforming layer having a composition
different from that of the anode layer and comprising a catalyst for
promoting a hydrocarbon steam reforming reaction and a component, or a
precursor of such a component for alleviating carbon deposition on the
hydrocarbon reforming layer.
