Abstract
A technique to provide fuel to a solid oxide fuel cell with low water consumption is described that includes providing an initial fuel mixture with air and hydrocarbon, and partially oxidizing the fuel mixture with a catalyst to provide a reformed fuel mixture. Also included is adding an amount of water to the reformed fuel mixture to reduce formation of elemental carbon from carbon monoxide in the reformed fuel mixture and supplying a portion of the reformed fuel mixture combined with water to an electrochemical device that produces electrical power from hydrogen in the reformed fuel mixture.
