초록

A gasket is provided on a porous sheet in one body. The gasket is thin and has an excellent sealability, and processability when the gasket is built in layer-built fuel cells. The gasket is made of liquid rubber and has a hardness not more than 60 (JIS A). Liquid perfluoro rubber and liquid silicone rubber is preferably used for the gasket. And gasket can be made by injection molding.

청구항

1. A method for making a gasket on a sheet for a layer-built fuel cell, said method comprising the steps of; preparing at least two molds having a groove by which the gasket is formed, wherein the molds have a sealing means around a peripheral portion thereof, a passage through which air can flow out of the molds and an inlet on one of the molds through which the liquid rubber can flow into the groove, placing a porous carbon sheet between the two molds and closing the molds so that the sealing means on one of the molds contacts a surface of the othe...
