Beschreibung
Zusammenfassung:	A membrane electrode assembly (10) includes an anode (16); a cathode (14), a membrane (12) between the anode and the cathode; and a protective barrier layer (22) between the membrane and at least one of the anode and the cathode, the protective barrier layer being adapted to restrict migration of at least one of oxygen and hydrogen from the anode and/or cathode to the membrane. The barrier layer keeps a plane of polarized charge (Xo) outside of the membrane and helps avoid formation of disconnected catalyst.
