The invention relates to internal-reforming fuel cells. They are each constructed of plural unit cells stacked one over another. Each unit cell is formed of a cathode, an electrolyte plate, an anode and a separator. Each unit cell also includes a generating zone formed by the cathode, anode and electrolyte plate; a reforming zone for reforming fuel gas; a fuel gas flow channel communicating with a fuel gas inlet and a fuel gas outlet and including a divided fuel gas flow channel for the unit cell; and an oxidant gas flow channel communicating with an oxidant gas inlet and an oxidant gas outlet and including a divided oxidant gas flow channel for the unit cell. The reforming zone is arranged in the fuel gas flow channel while the generating zone is arranged in contact with the fuel gas flow channel and the oxidant gas flow channel at a position downstream of the reforming zone while the fuel gas and oxidant gas are maintained separated from each other.
An internal reforming fuel cell comprising a plurality of unit cells stacked together in a first direction, each of said unit cells comprising a cathode an anode and an electrode plate therebetween, and a separator;
An internal-reforming fuel cell comprising a plurality of unit cells stacked together in a first direction, each of said unit cells comprising a generating zone and a reforming zone adjacent said generating zone in a second direction perpendicular to said first direction, wherein said generating zone includes a cathode, an anode and an electrode plate therebetween, and wherein said reforming zone includes a reforming catalyst for reforming a fuel gas.
In a power station for generating power including a fuel cell, a fuel gas source and an oxidant gas source, the improvement wherein said fuel cell comprises an internal-reforming fuel cell comprising a plurality of unit cells stacked together in a first direction, each of said unit cells comprising a generating zone and a reforming zone adjacent said generating zone in a second direction perpendicular to said first direction, wherein said generating zone includes a cathode, an anode and an electrode plate therebetween, and wherein said reforming zone includes a reforming catalyst for reforming a fuel gas.
