METHOD FOR COATING A SEALANT ON A FUEL CELL SEPARATOR

A method for coating a sealant on a separator for a fuel cell in which a sealing groove (118), in which a sealant (39) is coated, is provided in a separator (40), and widths of the sealing groove at a coating-start portion (39a) and a coating-end portion (39b) of the sealant are made greater than widths of portions other than the coating-start portion and the coating-end portion, and the coating-start portion and the coating-end portion of sealant are made to intersect at a place where the width of the sealing groove is made large. Adhesion between the coating-start portion and the coating-end portion is improved, and also, degrees of freedom of a sealant coated position increase, and sealability of a cell for a fuel cell is improved.
