A novel, low-cost mesoporous Si 3N 4 selective gas separation material was tested as a hydrogen clean-up membrane to remove CO from simulated feed gas to single-cell PEMFC, employing Nafion as the polymer electrolyte membrane. Polarization and power density measurements and gas chromatography showed a clear effect of separating the CO from the gas mixture; the performance and durability of the fuel cell was thereby significantly improved. %K Al2O3 disk supported Si3N4 membrane %K hydrogen purification %K CO removal %K fuel cells %K Pt catalyst %U http://www.mdpi.com/2077-0375/3/4/406
