Abstract:
1. A fuel cell system for generating electricity by combination of oxygen with hydrogen-containing fuel, comprising: a) a fuel cell stack including cathodes and anodes; b) a catalytic reformer for reforming hydrocarbon to provide hydrogen-containing reformate fuel to said stack, and c) a combuster, wherein said stack exhausts syngas and cathode air, and wherein said system is configured to recycle a first portion of said exhausted syngas into said reformer, said first portion being about 20% to about 60% of said syngas exhausted from said stack, and wherein said system is configured to recycle said cathode air and a second portion of said exhausted syngas into said combustor so that said second portion of said exhausted syngas and said cathode air are combusted to provide heat for reforming hydrocarbon in said catalytic reformer.
