Abstract
A fuel cell system and method is provided to control the volumetric ratio of a reformate and unreformed hydrocarbon fuel supplied to a fuel cell configured for in-stack reforming. The system includes a reformer having a number of high and low steam reforming activity channels which provide a full equilibrated fuel stream and a fuel stream having hydrocarbon levels slight lower than the hydrocarbon levels of the hydrocarbon fuel supplied to the reformer, respectively. The fuel streams can be mixed and supplied to the fuel cell to provide in-stack reforming while reducing or inhibiting the formation of carbon in the fuel stack.
