摘要： A spring loaded direct oxidation fuel cell assembly reduces the effects of precompression relaxation. A near flat spring and a distribution plate form a spring assembly that is disposed between a membrane electrode assembly and one of the current collectors in the fuel cell. The components are assembled into a fuel cell assembly and are precompressed, and a spring yielding process is performed. While precompression is being applied, a set of pins and a plastic frame are insert molded around the fuel cell assembly to hold the components in place. Subsequently, as the precompression relaxes, the spring assembly forces act to maintain an evenly distributed compression on the MEA, thereby compensating for the loss of precompression. A related method of manufacturing a fuel cell assembly is provided.

摘要： 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.
