Abstract
A membrane electrode assembly for a fuel cell includes an anode catalyst layer, a cathode catalyst layer, and an ion conducting membrane. The ion conducting membrane is interposed between the anode catalyst layer and the cathode catalyst layer. The ion conducting membrane includes an ion conducting polymer having sulfonic acid groups and rubber particulates. Characteristically, the rubber particulates have an average spatial dimension less than about 600 nanometers. A fuel cell incorporating the membrane electrode assembly is also provided.
