Abstract: An apparatus for carrying out a multi-step process of converting hydrocarbon fuel to a substantially pure hydrogen gas feed includes a plurality of reaction zones arranged in a common reaction chamber. The multi-step process includes: providing a fuel to the fuel processor so that as the fuel reacts and forms the hydrogen rich gas, the intermediate gas products pass through each reaction zone as arranged in the reactor to produce the hydrogen rich gas.

Abstract: An apparatus for carrying out a multi-step process of converting hydrocarbon fuel to a substantially pure hydrogen gas feed includes a plurality of reaction zones arranged in an insulated, box-shaped, compact fuel processor. The multi-step process includes preheating the hydrocarbon fuel utilizing integration with the inherent exothermic processes utilized with the fuel processor, reacting the preheated hydrocarbon fuel to form the hydrogen rich gas, and purifying the hydrogen rich gas to produce a gas that is suitable for consumption in a fuel cell.
