ABSTRACT:
A pair of reaction vessels provide hydrogen to a fuel cell by making hydrogen in one of the vessels while simultaneously regenerating the other vessel, and then reversing the function of the vessels. In the vessel making hydrogen a hydrocarbon feedstock is cracked and steam reformed using sensible heat generated during the regeneration of the vessel. Regeneration includes preheating, separately within the reaction vessel, fuel cell fuel electrode exhaust and an oxygen containing gas. Preheating is accomplished using the heat of combustion and/or sensible heat stored within material disposed within the vessel while it is making hydrogen. After being preheated the fuel electrode exhaust and oxygen containing gas are allowed to mix and combust within the vessel, thereby heating materials disposed therein. This heat is the heat used to crack and steam reform the hydrocarbon fuel.
