Abstract:
Methods for manufacturing laminated membranes for MEAs, such methods comprising (i) providing a substrate, a catalyst ink fluid, and a first membrane fluid; (ii) providing a second membrane fluid; (iii) simultaneously coating the catalyst ink fluid onto the substrate, the first membrane fluid onto the catalyst ink fluid, and the second membrane fluid onto the first membrane fluid; and (iv) applying a reinforcement layer (such as ePTFE) and allowing for full imbibement. The second membrane fluid (i) consists of alcohol or (ii) is an alcohol-rich fluid comprising polymer electrolyte.
