Abstract:
1. A solid oxide fuel cell system comprising: an elongated stack having a first end and a second end, the stack including a plurality of tubular cells, each cell having an inner radius configured as an anode electrode portion and an outer radius configured as a cathode electrode portion; a support plate for retaining the stack; a feed can coupled to the support plate to form an anode feed plenum adjacent the first end of the stack; a fuel processing reactor in fluid communication with the anode feed plenum for receiving a hydrocarbon fuel and air mixture to provide a rich fuel anode feed stream to the anode feed plenum, wherein the anode feed plenum is in fluid communication with the stack so that the anode feed stream passes through the tubular cells to become an anode exhaust; an exhaust end tube sheet; an exhaust can depending from the exhaust end tube sheet, the exhaust can defining an anode exhaust hold; and a cathode chamber can depending from the support plate and, surrounding the stack and the exhaust can, the cathode chamber can defining an exhaust gas hold near the anode exhaust hole to form a region in which the anode exhaust and the cathode exhaust mix to form a mixed exhaust stream.
