NOVELTY - The solid oxide fuel cell (100) useful in a system for generating electricity, comprises an electrolyte (106), a cathode (102) disposed on a first side of the electrolyte, and a sulfur tolerant anode (104) disposed on a second side of the electrolyte and opposite to the cathode. The sulfur tolerant anode is configured to exhibit a stable operating voltage in the presence of a fuel with a measurable sulfur content of greater than 50 ppmv and to facilitate direct oxidation of a hydrocarbon fuel in the absence of a process to reform the hydrocarbon fuel to a synthesis gas.    USE - The solid oxide fuel cell is useful in a system (claimed) for generating electricity from reformate of synthesis gas and sulfur content and from unreformed hydrocarbon fuel.    ADVANTAGE - The solid oxide fuel cell exhibits stable operating voltage, improved electrochemical performance and high conductivity thus achieving a stable output power.    DETAILED DESCRIPTION - The solid oxide fuel cell (100) useful in a system for generating electricity, comprises an electrolyte (106), a cathode (102) disposed on a first side of the electrolyte, and a sulfur tolerant anode (104) disposed on a second side of the electrolyte and opposite to the cathode. The sulfur tolerant anode is configured to exhibit a stable operating voltage in the presence of a fuel with a measurable sulfur content of greater than 50 ppmv, to facilitate direct oxidation of a hydrocarbon fuel in the absence of a process to reform the hydrocarbon fuel to a synthesis gas, and to electrochemically oxidize the synthesis gas in the presence of sulfur content. The stable operating voltage is within 20 mV of a sulfur-free operating voltage of the fuel cell. The composition of the sulfur tolerant anode comprises an electrochemically inert ceramic oxide finely dispersed within a metallic phase of the sulfur tolerant anode. The metallic phase comprises nickel to contribute an oxidation of hydrogen and carbon monoxide, and copper to contribute an oxidation of a hydrocarbon. The ceramic oxide and the ceria contribute to sulfur tolerance and coke resistance of the sulfur tolerant anode. A catalyst is disposed with the sulfur tolerant anode to contribute to the sulfur tolerance of the anode, and is infiltrated into a surface of the anode. The sulfur tolerant anode comprises a graded ceria anode and a graded copper anode. A proportional concentration of the ceria and the yttria-stabilized zirconia within the sulfur tolerant anode varies relative to a distance from the electrolyte in the graded ceria anode. A copper concentration within the sulfur tolerant anode varies along a distance between a fuel input end- and a fuel output end of the sulfur tolerant anode in the graded copper anode. INDEPENDENT CLAIMS are included for:    (1) a solid oxide fuel cell system; and    (2) a method for making a solid oxide fuel cell.
