Bipolar plate manufacturing method for e.g. hydrogen cell, involves inserting temperature-resistant sealing into groove before manufacturing process, where rod is provided in outer region of plate and leaves groove in plate after assembling

摘要

The method involves utilizing all types of injection molded or pressed fluorine-elastomer compounds as material. A groove is provided in an outer region of a bipolar plate, and a temperature-resistant sealing is inserted into the groove before the manufacturing process. The sealing is stably positioned in the material during the manufacturing process, and a material made of fluorine-elastomer is utilized as the sealing and is produced from injection molded or pressed fluorine-elastomer. A rod is provided in the outer region of the plate, and leaves the groove in the plate after assembling.
