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.
