Perfluorosulfonate lonomer Film-coated Platinized

1 Perfluorosulfonate lonomer Film-Coated Platinized Carbon Electrodes for Oxygen Reduction [Pg.38]

To improve the performance of low temperature fuel cell systems, effort has been devoted to improving the kinetics of oxygen reduction on platinum at solid polymer electrolyte interfaces. Polymer electrolyte materials, including polyperfluorosulfonic acid polymers such as Nafion -H, have been Incorporated [Pg.38]

Martin et have evaluated the concentration and diffusion coefficients of O2 in commercial perfluorosulfonate ionomer (Nafion ) materials to assess [Pg.39]

Shukla and coworkers have reported the optimization of porous carbon electrodes that are dispersed with platinum catalyst and is bound to Nafion membranes for oxygen reduction. In an earlier optimization study, it [Pg.39]

Much of the earlier work involving acid electrolyte-based fuel cells was conducted with noble metals systems which displayed superior performance at higher temperatures and led to the use of concentrated H3PO4 (85-98%), which allows temperatures of operation up to 190 Applepy has delineated [Pg.40]
