SEALING MATERIAL COATING METHOD FOR FUEL CELL-USE SEPARATOR

摘要

A method of applying a sealing material onto a fuel cell-use separator, wherein a seal groove (118) to which a sealing material (39) is applied is provided in a separator (40), the width of the seal groove is so set as to b e larger at a portion (39a) where a sealing material application starts and a portion (39b) where a sealing material application ends than at the other portions, and the application starting portion and the application ending portion are allowed to cross each other at portions where a seal groove widt h is larger, whereby enhancing adhesion between the application starting porti on and the application ending portion, a degree of freedom of sealing material applying position, and the sealing performance of a fuel cell-use cell.
