In this work, the effect of Pt-Cs2.5 addition on the durability of nanocomposite membranes has been investigated. The Fenton’s test and OCV measurements were used for evaluation of the chemical and oxidative stability of these membranes. The residual weight of nanocomposite membrane having 15 wt.% catalyst increase to over 40 percent after the Fenton’s test. Also, in the OCV measurements, a 16 % decrement observes in voltage loss. These results indicate that by addition of Pt-Cs2.5 nanoparticles into sPEEK polymer matrix, the oxidative durability of nanocomposite membranes has been improved
