Abstract
Official abstract text for this publication.
A method of coating carbon based electrodes and thick electrodes without mud-cracking is described. The electrode ink is deposited on a decal substrate, and transferred to a hot press before the electrode ink is completely dried. The partially dried electrode ink is hot pressed to the membrane to form a membrane electrode assembly. A membrane electrode assembly including a polymer membrane; and a pair of crack-free electrode layers on opposite sides of the polymer membrane, each of the pair of electrode layers having a thickness of at least about 50 μm is also described.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of fabricating a membrane electrode assembly comprising: depositing a layer of electrode ink on a decal substrate; placing the decal substrate on one side of a porous graphite plate; partially drying the electrode ink by applying a vacuum to one side of said porous graphite plate until no visible liquid remains on the surface to form an electrode layer that has a uniform thickness of at least about 120 microns thick without using extra additives…
