Abstract

A membrane and electrode structure is formed by applying ink of catalytically active particles on the surface of the membrane. The electrode ink comprises: PA1 (a) catalytically active particles; PA1 (b) a hydrocarbon having at least one ether, epoxy or ketone linkage and an alcohol group, preferably 1 methoxy 2 propanol; and PA1 (c) optionally, perfluorinated sulfonyl fluoride polymer or perfluorinated sulfonic acid polymer.
