A solid-oxide fuel cell system wherein a reformate combustor is disposed in the reformate flow path between a hydrocarbon reformer and a fuel cell stack. At system start-up, reformate is partially burned within the combustor by admitting combustion air, and the partially-burned reformate is passed through the anode chambers of the stack to warm the anodes. In addition, reformate is passed through a cathode-air heat exchanger to warm combustion air entering the cathode chambers of the stack. The combustor may continue to be supplied with a low level of ai...
What is claimed is: 1. A solid oxide fuel cell system, comprising: a) a fuel cell stack including cathodes and anodes; b) a hydrocarbon reformer for providing reformate to said anodes; c) a combustor operationally disposed between said reformer and said stack for controllably adding a volume of air to said reformate to partially combust said reformate to provide moisture and heat to said anodes; and d) a heat exchanger operationally disposed between said combustor and said stack such that said partially-combusted reformate may be passed through a first ...
