    摘要: A method for coating a sealant (39) on a separator (40) for a fuel cell. The separator has a sealing groove (118) formed therein, 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 remaining portions of the sealing groove. The sealant coating-start portion and the coating-end portion are made to intersect at a place where the width of the sealing groove is 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.
