1. A method for coating a sealant on a separator for a fuel cell, comprising the steps of:
preparing a separator having a gas flow path and a water flow path;
preparing a sealant coating apparatus for coating a liquid sealant at a periphery of the gas flow path and the water flow path of the separator, said sealant coating apparatus including a nozzle portion;
at a coating-start portion of the sealant, making the nozzle portion be relatively closer to the separator than at portions other than the coating-start portion; and
at the coating-start portion of the sealant, moving the nozzle portion at a horizontal moving velocity that is relatively slower than at the portions other than the coating-start portion.
