A novel catalyst with high activity and poisoning tolerance

Stanford researchers have patented a low-cost highly active catalyst that is stable over time and in different chemical environments. This catalyst has a number of advantages over platinum the current favored catalyst used in fuel cells. The cost of the materials is roughly 1/10000 the cost of platinum meaning this catalyst could dramatically reduce the cost of fuel cells (currently the material cost of the platinum catalyst may be up to 25% of the entire system cost). This catalyst is also more stable than platinum when operated over long times at high temperature and is much more resistant to CO and H2S poisoning than are platinum or nickel (another popular catalyst). These compositions have been experimentally tested in solid oxide fuel cell and proton exchange membrane fuel cell configurations. Stage of Research: Proof-of-concept Applications: 1) Fuel cells particularly Solid Oxide Fuel Cells (SOFCs) 2) Electrolyzer applications 3) Effective for anode and cathode half-reactions


1) Dramatically lowers the cost of the fuel cell since this material\'s cost is roughly 1/10000 of platinum 2) High activity 3) Longer lifetime of catalyst 4) Low surface energy implying high stability to ripening over time 5) High tolerance for anode poisons CO and H2S
