ABSTRACT:
A method for fabricating membrane electrode assembly includes providing an anode side diffusion layer structure and a cathode side diffusion layer structure with a layer of membrane electrolyte therebetween. The diffusion layer structures include diffusion segments, which are coupled to each other by a first engaging member having one or more portions configured for engagement with a feed or aligning mechanism. Also, one or more of the segments of the diffusion layer structures may be connected to other segments or the first engaging member by one or more bridges. Bridges of each diffusion layer structure may be offset to avoid electrical contact with each other in response to diffusion layer structures being assembled with each other and with the layer of membrane electrolyte.
