Abstract: A thermally integrated hotbox apparatus combining a steam reformer, a plurality of solid oxide fuel cell (SOFC) stacks, a plurality of oxidant manifolds, and at least one heat extractor. The steam reformer occupies a central position in the hotbox, around which are disposed in spaced-apart relation a plurality of SOFC stacks. A burner may be associated with the steam reformer, either within or outside the hotbox. An oxidant manifold is disposed between each pair of adjacent SOFC stacks. A heat exchanger is incorporated between an SOFC stack and an oxygen manifold. The hotbox design optimally captures thermal heat from the SOFC stacks for use in producing steam and operating the endothermic steam reformer. The apparatus reduces duty cycle of the burner, which produces heat and steam needed for operation of the endothermic steam reformer.

Abstract: An integrated power generation system including: a hotbox containing a steam reformer and at least one solid oxide fuel cell (SOFC) stack; a condenser, a combustor, a heater, and a turbomachine comprising a compressor and an expander. The steam reformer is configured to convert a hydrocarbon fuel and steam into a stack fuel. The SOFC stack is configured to convert the stack fuel into a first anode waste gas. The condenser functions to remove water from the first anode waste gas, thereby producing a second anode waste gas of higher fuel energy density. The combustor bums the second anode waste gas with release of exothermic heat. The heater thermally transmits heat from an expanded combustion product to water collected in the condenser, so as to generate steam. A steam line fluidly connects the heater to the steam reformer.
