ELASTIC BODY GASKET SUCH AS FUEL CELL PLATE, FUEL CELL PLATE FORMED INTEGRALLY WITH ELASTIC BODY GASKET, AND METHOD OF MANUFACTURING THE GASKET AND THE PLATE

摘要

An elastic body gasket put on the surface of a plate such as a fuel cell plate, a fuel cell plate formed integrally with the elastic body gasket, and a method of manufacturing the gasket and the plate. The elastic body gasket, wherein a large number of gas and cooling water passage grooves (2) are formed at the center thereof, gas and cooling water lead-in and lead-out manifold holes (3) and (4) are formed on both outer sides of the passage grooves (2), lead-in parts and discharge parts are formed between the manifold holes (3) and (4) and the passage grooves (2), and flat plates capable of forming tunnel-structure passages are fitted to the lead-in parts and the discharge parts. The flat plates can be tightly fixed and the leakage of fluid from the fitting parts of the flat plates to the outside can be completely sealed, a productivity can be increased, and the consumed amount of a raw material can be reduced to reduce cost.
