    Abstract: A method for improving the efficiency of a hydrocarbon catalytic reformer and close-coupled fuel cell system by recycling a percentage of the anode exhaust syngas directly into the reformer in a range between about 20% and about 60%. Oxygen is supplied to the reformer (12) at start-up. Under equilibrium conditions, oxygen required for reforming of hydrocarbon fuel is derived entirely from endothermic reforming of water and carbon dioxide in the recycled syngas. Recycling of anode syngas into the reformer increases fuel efficiency, adds excess water to the reformate to increase protection against anode coking, and protects the fuel cell stack (16) against air- and water-borne contaminants. A method for producing an excess amount of syngas for exporting for other purposes is also provided.

    Abstract: A fuel cell (10,12,55,65,70,70',70") having a non-uniform electrical resistivity over the flow area of the cell. Resistance is higher in areas of the cell having locally low levels of hydrogen than in areas having locally high levels of hydrogen. Excess oxygen ion migration and buildup is suppressed in regions having low hydrogen concentration and is correspondingly increased in regions having a surfeit of hydrogen. Destructive oxidation of the anode is suppressed and a greater percentage of the hydrogen passed into the cell is consumed, thereby increasing electric output.
