초록

A hybrid SOFC/gas turbine electric generating system comprising an SOFC stack, a hydrocarbon reformer, a first anode tailgas hydrogen-rich combustor to drive a first gas turbine stage, and a second stoichiometric combustor to drive a second gas turbine stage to drive a generator. Anode tailgas is also recycled into the reformer for substantially endothermic reforming of hydrocarbon fuel. Oxidant is provided as pure oxygen—which may be stored as liquid oxygen. All nitrogen may be excluded. Cathode exhaust is passed to the first combustor, to the se...

청구항

What is claimed is: 1. A system for generating electricity, comprising: a) a hydrocarbon reformer for producing reformate from hydrocarbon fuel; b) a fuel cell stack having anodes and cathodes for consuming said reformate to produce a first electric output, an anode tail gas, and a cathode tail gas; c) a source for providing oxygen as an oxidant for said system; d) a combustor for combusting at least a first portion of said anode tail gas with oxygen to produce a combustor tail gas, said combustor comprising a first combustor for combusting at least a p...
