Abstract
A separator to be used in a fuel cell includes a gas flow path including a plurality of gas flow path grooves that allow reactive gas to flow; a gas discharge hole used for discharging the reactive gas from the gas flow path; and an outlet flow path part positioned between the gas discharge hole and the gas flow path and used for flowing the reactive gas discharged from the gas flow path into the gas discharge hole. The plurality of gas flow path grooves includes a coupling flow path part coupled to the outlet flow path part. The coupling flow path part includes tilted gas flow path grooves tilted from a direction of gravitational force. A groove width of the tilted gas flow path groove in the coupling flow path part is set such that a force of a wall surface of the tilted gas flow path groove to retain water by means of a surface tension of the water is larger than a force applied to the water by the gravitational force.
