Abstract

A solid oxide fuel cell system includes a solid oxide fuel cell stack, a fuel supply inlet conduit adapted to provide a hydrocarbon fuel inlet stream into the solid oxide fuel cell stack and a fuel exhaust outlet conduit adapted to remove a fuel exhaust stream from the solid oxide fuel cell stack. The system also includes a water vapor and enthalpy recovery unit operatively connected to the fuel supply inlet conduit and to the fuel exhaust outlet conduit. The water vapor and enthalpy recovery unit is adapted to selectively transfer at least a portion of water vapor and heat from the fuel exhaust stream to the hydrocarbon fuel inlet stream. The system also includes a hydrogen recovery unit connected to the fuel supply inlet conduit and to the fuel exhaust outlet conduit. The hydrogen recovery unit is adapted to selectively transfer at least a portion of hydrogen from the fuel exhaust stream to the hydrocarbon fuel inlet stream.
