    Impact of ionomer content on proton exchange membrane fuel cell performance
    (Wiley, 2015-12-03) Afsahi, Foroughazam; Mathieu-Potvin, François; Kaliaguine, S.
    The effect of Nafion ionomer content on performance of a proton exchange membrane (PEM) fuel cell operated with home-made anodic and cathodic electrodes fabricated from a novel metal organic framework (MOF) derived Pt-based electrocatalyst was investigated via numerical simulation and experimental measurement. First, the parameter sensitivity analysis was performed to identify the most influential parameters of the model. Then, these parameters were calibrated for different fuel cell designs investigated in the current study by employing the corresponding experimental data. Afterwards, the calibrated model was used to examine the impact of Nafion content in the catalyst layer of home-made electrodes. Finally, the qualitative trend predicted by this model was experimentally surveyed by varying the Nafion content between 10–50 wt.% in the catalyst layer of home-made electrodes. At the anode side, the performance of home-made electrode in a PEM fuel cell demonstrated small dependency on Nafion content. For the cathodic home-made electrode, Nafion content was found to affect the PEM fuel cell performance more strongly. Although the model could correctly capture the impact of Nafion content on calculated polarization curves, the model predicted optimum values significantly deviate from the experimental results. This was related to the several simplifications made during model development.
