Abstract

We investigate in detail the influence of O, S, and N functionalization of Pt₃Co/C catalysts on the proton exchange membrane fuel cell (PEMFC). The results demonstrated that N-functionalization is more beneficial for the distribution of the ionomer in the catalyst layer, resulting in a trade-off between oxygen and hydronium ion transport.
