SULFUR TOLERANT ANODE FOR SOLID OXIDE FUEL CELL

摘要

A solid oxide fuel cell (SOFC) (100) for use in generating electricity while tolerating sulfur content in a fuel input stream. The solid oxide fuel cell (100) includes an electrolyte (106), a cathode (102), and a sulfur tolerant anode (104). The cathode (102) is disposed on a first side of the electrolyte (106). The sulfur tolerant anode (104) is disposed on a second side of the electrolyte (106) opposite the cathode (102). The sulfur tolerant anode (104) 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 (100) is useful within a SOFC stack to generate electricity from reformate which includes synthesis gas (syngas) and sulfur content. The solid oxide fuel cell (100) is also useful within a SOFC stack to generate electricity from unreformed hydrocarbon fuel.
