Abstract

See full text

A membrane electrode assembly is provided for use in a fuel cell and utilizes an external manifold and seal structure which are molded directly to the gas diffusion layers. The integrated manifold and gas diffusion layers are formed as duplicate components which can be oriented 180 degrees offset to one another to create the MEA assembly with a catalyst coated membrane disposed therebetween. The integrated manifold and seal structures can be held together by heat pressing or other known connection techniques.
