The impact of the Pt band on ionomer degradation is controversial. Many studies found increased degradation in the presence of Pt deposits. However, in a recent publication, it was reported that the Pt band suppressed ionomer degradation.3 In their theoretical work, Gummalla et al. explained this discrepancy by the distribution of Pt particles: at low particle density, radicals are free to attack the ionomer, at high density, they are scavenged.4 Experimental results based on membranes in which Pt was deposited chemically support this theory.5,6 However, in those membranes, Pt particles were dispersed homogeneously, not locally as a thin band. In order to examine the influence of the Pt band more accurately, it is necessary to prepare membr...
