FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering, specifically to a solid-oxide fuel cell based combined cycle system. 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 fuel cell tail gas downstream of fuel cell and partly or fully converts hydrocarbon fuel into hydrogen (H) and carbon monoxide (CO), wherein fuel path diverts a first portion of reformed fuel to inlet of fuel cell anode. Fuel cell includes an Organic Rankine cycle (ORC) configured to remove heat from a residual portion of reformed fuel and to deliver cooled residual portion of 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 cooled residual portion of reformed fuel.EFFECT: increased efficiency of combined cycle fuel cell.24 cl, 4 dwg |
