Abstract
A solid oxide fuel cell (SOFC) for use in generating electricity while tolerating sulfur content in a fuel input stream. The solid oxide fuel cell includes an electrolyte, a cathode, and a sulfur tolerant anode. The cathode is disposed on a first side of the electrolyte. The sulfur tolerant anode is disposed on a second side of the electrolyte opposite the cathode. The sulfur tolerant anode includes a composition of nickel, copper, and ceria to exhibit a substantially stable operating voltage at a constant current density in the presence of the sulfur content within the fuel input stream. The solid oxide fuel cell is useful within a SOFC stack to generate electricity from reformate which includes synthesis gas (syngas) and sulfur content. The solid oxide fuel cell is also useful within a SOFC stack to generate electricity from unreformed hydrocarbon fuel.
