Abstract
The present invention relates to an anode catalyst for use in the electrochemical oxidation of HS to elemental sulfur and water, specifically in a fuel cell having an ion-conducting membrane. The catalyst comprises a material prepared from two or more metal sulfides of the formula MS, wherein M is selected from the group consisting of Co, Ni, Fe, Mo, Cu, Cr, W and Mn, and x is between about 1.0 and about 2.5; a conductive material suitable for fuel cell operation; and a porous material. The invention further provides methods of preparing the catalyst, fuel cells comprising the catalyst and methods of electrochemically oxidizing HS using the catalyst.
