Title:
MEMBRANE ELECTRODE ASSEMBLIES FOR DIRECT METHANOL FUEL CELLS AND METHODS FOR THEIR PRODUCTION
Document Type and Number:
WIPO Patent Application WO2002039533
Kind Code:
A3
Abstract:
A method of producing a membrane electrode assembly (1) for use in direct methanol fuel cells by serigraphically printing cathode catalysts (3) or anode catalysts (6) with a carbon baking layer (4, 7) onto graphite or carbon paper (5, 8), boiling impurities from these layers, and bonding the boiled, printed cathode and anode catalyst layers onto opposite sides of a polymer electrolyte membrane (2) via semi-isostatic compression in a constraint which restricts volume and lateral defamation is provided. Also provided are membrane electrode assemblies produced in accordance with this method.
