Electrochemical Impedance Aided Optimisation strategy for PEM Fuel Cells Operated with Non-Precious-Metal Catalysts. Figure 1: RDE plots showing the performance of different catalysts and SEM Cross section of MEA to illustrate the thickness of the catalyst layer Figure 2: High resolution SEM images of catalyst layer cross section at different ionomer content. Figure 3: Comparing the effect of I/C ratio on the performance of a fuel cell using different catalysts. Figure 4: H2/Ar impedance spectra showing the Nyquist and Bode Phase plots of the three catalysts with different I/C ratios at 0.1 V cell potential. Bode Magnitude Plots can be found in the Supplementary Information Figure 5: H2/O2 impedance plots for the 3 catalysts in the kinetic region (0.6V)
