Abstract: A fuel cell system having a cathode, anode and auxiliary loop is provided. The anode loop may be configured to deliver reformed and unreformed fuel to the fuel cells. Unreformed fuel may be provided to the fuel cells by bypassing a portion of the fuel around a reformer. The unreformed fuel may be reformed in the fuel cell block. The cathode loop may direct a portion of oxidant exhausted from said fuel cells back to the fuel cell through a cathode ejector. The ejector may be supplied with pressurized oxidant that may be heated prior to entering the cathode ejector. The auxiliary loop may combust unused fuel and oxidant to provide the heat transferred to the oxidant prior to the oxidant entering the cathode loop.

Abstract: A fuel cell unit with a plurality of fuel cells defining a longitudinal axis and a main flow direction coaxial to the longitudinal axis. Fuel cell inlets and fuel cell outlets are arranged at opposite ends of the fuel cell unit and in line with the main flow direction. Also, a component comprising first fluid conduits arranged parallel to the main flow direction, the first fluid conduits comprising first fluid inlets and first fluid outlets arranged at opposite ends of the component and in line with the main flow direction. The component is arranged adjacent the fuel cell unit such that at least one of the first fluid inlets and the first fluid outlets of the component are arranged adjacent at least one of the fuel cell outlets and the fuel cell inlets such that a fluid flow may flow substantially parallel to the longitudinal axis of the apparatus in the first fluid conduits of the component and in the fuel cell unit and when passing from the component to the fuel cell unit or vice versa.

Abstract: There is disclosed a high temperature fuel cell system incorporating off-gas anode loop recycling and reforming. The fuel cell system includes a fuel cell stack having an anode inlet for fuel and an anode outlet for off-gas. A recycling device is configured to receive at least a portion of the off-gas from the anode outlet and to mix the portion of the off-gas with hydrocarbon fuel from a primary hydrocarbon fuel stream so as to form a reformable mixture. A reformer is configured to receive the reformable mixture from the recycling device and to generate a reformed fuel stream by reforming the reformable mixture. The fuel cell system is provided with a secondary hydrocarbon fuel stream and the reformed fuel stream and the secondary hydrocarbon fuel stream are supplied to the anode inlet of the fuel cell stack.
