    摘要: A combined cycle fuel cell includes a fuel cell such as a solid-oxide fuel cell (SOFC) comprising an anode that generates a tail gas. A hydrocarbon fuel reforming system that mixes a hydrocarbon fuel with the fuel cell tail gas downstream of the fuel cell partly or fully converts the hydrocarbon fuel into hydrogen (H2) and carbon monoxide (CO). A fuel path diverts a first portion of the reformed fuel to the inlet of the fuel cell anode. A cooler such as an Organic Rankine cycle (ORC) is optionally configured to remove heat from a residual portion of the reformed fuel and to deliver the cooled residual portion of the reformed fuel to a bottoming cycle that may be an external or internal combustion engine such as a reciprocating gas engine or gas turbine that is driven in response to the cooled residual portion of the reformed fuel.
