Ionic Conductivity of PEMFC Electrodes: Effect of Nafion Loading [proton exchange membrane fuel cell]

The effect of Nation loading in the cathode catalyst layer of proton exchange membrane fuel cell (PEMFC) electrodes was studied by impedance spectroscopy, cyclic voltammetry, and polarization experiments. Catalyst utilization, determined by cyclic voltammetry, peaked at 76% for a Nafion loading of c...
