Abstract
A membrane and electrode structure is formed by surface hydrolyzing an ion exchange membrane and then applying electrode ink of catalytically active particles on the surface of the membrane. The membrane and electrode structure of the present invention is particularly useful in fuel cells and batteries. The inventive process prevents the membrane from swelling or distorting following application of the electrode ink and also improves adhesion between the electrode ink layer and the surface of the membrane.
