<div>Use of pseudo-2d simulations to understand microstructure-performance relationships in PEMFC cathode catalyst layers.</div><div><br></div><div>Prepared and presented by Corey Randall at 235th Electrochemical Society Meeting, Dallas, TX, May 29, 2019.<br></div><div><br></div><div>By estimating Nafion structure-property relationships from previously published data, we are able to capture changes to the limiting current with varying Pt loading. However, there remains a kinetic limitation, which scales linearly with Pt loading, which the model does not currently capture. <br></div><div><br></div><div>Results also predict non-monotonic variation of PEMFC performance with variations in the Nafion catalyst coating thickness within the catalyst layer.</div>
