Patent ID: 6933003

Claim:
A method useful for making a membrane electrode assembly comprising: providing a non-porous substrate comprising a metallic film that is laminated to another film material which provides additional structural integrity, which substrate has sufficient structural integrity to be reusable; forming a slurry including an ionically conductive material, an electrically conductive material, a catalyst, and a solvent; applying the slurry onto the non-porous substrate; drying the applied slurry to form a first decal; bonding the first decal to a membrane; peeling the non-porous substrate from the first decal in a substantially undamaged condition; and reusing the non-porous substrate by applying the slurry onto the nonporous substrate, drying the applied slurry to form a second decal; bonding the second decal to a membrane and peeling the non-porous substrate from the second decal.
