FABRICATION AND TESTING OF A H-2-O-2 FUEL-CELL USING MOXRUYSEZ

We report the results obtained in the preparation and characterization of MoxRuySez electrocatalysts for oxygen reduction reaction and the d esign, construction and characterization of a H-2-O-2 fuel cell using MoxRuySez. The catalysts were characterized with respect to their elec trocatalytic properties. The fuel cell was designed and built with Mox RuySez supported on carbon as cathode, Pt supported on carbon as anode , and H2SO4 as the electrolyte. The fuel cell was tested at room tempe rature and atmospheric pressure. The H-2-O-2 cell showed an efficiency in the order of 30%.
