Abstract
A membrane electrode assembly for a fuel cell is disclosed, which comprises at least one porous ionomer containing layer disposed at the interface between the cathode electrocatalyst material and the ion exchange membrane of the fuel cell. The porous ionomer containing layer comprises a catalyst migration impeding compound. The membrane electrode assembly exhibits improved stability against Pt dissolution and Pt-band formation within the ion exchange membrane, hence having improved durability and lifetime performance.
