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.
On obtient une structure à membrane et à électrode en effectuant l'hydrolyse de surface d'une membrane à échange ionique et en appliquant une encre à électrode contenant des particules à activité catalytique sur la surface de la membrane. La structure à membrane et électrode de la présente invention convient particulièrement à des batteries et des piles à combustibles. Le procédé suivant l'invention prévient toute dilatation ou distorsion de la membrane après l'application de l'encre à électrode, tout en améliorant l'adhérence entre la couche d'encre et la surface de la membrane.
