Abstract: A method for coating a liquid sealant (61) at a periphery of a gas flow path and a water flow path on a separator for a fuel cell (57), including the steps of, at a coating-start portion (63) of the sealant, making a nozzle portion (33) provided at the sealant coating apparatus (24) be nearer to the separator than at portions other than the coating-start portion, and moving the nozzle portion at a horizontal moving velocity which is slower than at the portions other than the coating-start portion. By making the nozzle portion be near to the separator, pressing force pressing the sealant which is discharged from the nozzle portion against the separator becomes large, and turning up of a distal end portion of the sealant can be prevented by making the sealant adhere more to the separator. Further, by lowering the horizontal moving velocity of the nozzle portion, the sealant can be coated at a more uniform thickness.
