A thermally integrated fuel cell system includes a stack zone, a burner zone and a low temperature zone. The fuel is combined with steam and passed sequentially through a primary reformer and a secondary reformer or a radiative fuel heat exchanger. Air may be passed sequentially through an afterburner heat exchanger and a radiative air heat exchanger such that the radiative heat exchanger may be used to heat the stack zone. The stack exhaust is combusted in an afterburner. Afterburner exhaust heats the primary reformer, the high temperature air heat exchanger, the low temperature air heat exchanger and steam generator. The stack zone includes the stacks, the secondary reformer and the radiative heat exchanger. The burner zone includes the afterburner which includes a start burner, the primary reformer and the high temperature air heat exchanger. The low temperature zone includes the low temperature air heat exchanger and a steam generator.

Thermally integrated fuel cell system

A SOFC includes a cathode electrode, a solid oxide electrolyte, an anode electrode, and a hydrocarbon fuel inlet. The SOFC is configured for internal reforming of a hydrocarbon fuel at the anode electrode. The SOFC is configured to limit an interaction between the hydrocarbon fuel and the anode electrode adjacent to the hydrocarbon fuel inlet, or to limit an area of the anode electrode exposed to the hydrocarbon fuel adjacent to the hydrocarbon fuel inlet, or to provide a gradual introduction of the hydrocarbon fuel to the anode electrode.

A thermally integrated fuel cell system includes a stack zone, a burner zone and a low temperature zone. The fuel is combined with steam and passed sequentially through a primary reformer and a secondary reformer. Air is split into two parallel streams and preheated in a low temperature heat exchanger. One air stream passes to a high temperature heat exchanger while the other passes to a radiative heat exchanger. The air and fuel streams are equalized in an equalization heat exchanger before entering the fuel cell stacks. The stack exhaust is combusted in an afterburner. Afterburner exhaust heats the primary reformer, the high temperature heat exchanger, the low temperature heat exchanger and steam generator. The stack zone includes the stacks, the secondary reformer, the radiative heat exchanger and the equalization heat exchanger. The burner zone includes the afterburner, the primary reformer and the high temperature heat exchanger. The low temperature zone includes the low temperature heat exchanger and the steam generator.

Thermally integrated fuel cell stack

A stacked plate heat exchanger including a plurality of stacked plate pairs, each plate pair including first and second plates having elongate central portions surrounded by sealably joined edge portions with an elongate fluid passage defined between the central portions. Each plate pair has spaced apart inlet and outlet openings in flow communication with the fluid passage, at least some of the plate pairs having a substantially planar air-side fin plate extending peripherally outward from the joined edge portions, the fin plates of the stacked plate pairs being spaced apart and substantially parallel to each other. The fluid passage may be arranged at an angle relative to air flow direction.
