A method for coating a sealant () on a separator () for a fuel cell. The separator has a sealing groove () formed therein, and widths of the sealing groove at a coating-start portion () and a coating-end portion () 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.

Sealing material coating method for fuel cell-use separator

A membrane/electrode assembly trimming apparatus () made up of a lower trimming die () on which a membrane/electrode assembly () is set, an upper trimming die () having a trimming blade () and a pressing member () which is ascend/descendably suspended from this upper trimming die and suction-holds a carbon electrode (). A membrane/electrode assembly carrying apparatus () including a pressing member which suction-grips a carbon electrode and prevents it from slipping sideways is also disclosed. Because the certainty of the positioning, fixing and trimming of the membrane/electrode assembly at the time of trimming is raised and positional slipping of the trimmed membrane/electrode assembly during carrying can be prevented, the performance of the fuel cell improves.
