Abstract
A fuel cell manufacturing method is provided by which an unbroken strip of sheet material is sent through a molding process, an MEA assembly process and a modularization process, and is separated into individual modules in a batch process. In the molding process, separators are sequentially molded on the strip of sheet material, and a separator strip is produced in which the separators are connected together by runners. In the MEA assembly process and the modularization process, MEAs are sequentially assembled on the separator strip in which a series of the separators are connected together by the runners, and a module strip is produced in which a series of the modules are connected together by the runners. In the batch process, the series of modules is separated into the individual modules by cutting and removing the runners from the module strip.
