A high efficiency, multi-stage fuel cell system method and apparatus is provided. The fuel cell system is comprised of multiple fuel cell stages, whereby the temperatures of the fuel and oxidant gas streams and the percentage of fuel consumed in each stage are controlled to optimize fuel cell system efficiency. The stages are connected in a serial, flow-through arrangement such that the oxidant gas and fuel gas flowing through an upstream stage is conducted directly into the next adjacent downstream stage. The fuel cell stages are further arranged such t...
[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A method for operating a multi-stage fuel cell system, comprising the steps of:providing a plurality of fuel cell stages, each fuel cell stage having fuel and oxidant process stream inlets and outlets for conducting process streams through the fuel cell stage, and each fuel cell stage containing at least one fuel cell;designing each fuel cell stage to operate within a desired temperature range, such that the multi-stage fuel cell system...
