Abstract
A separator for a fuel cell, which is stacked on a reaction layer including a membrane electrode assembly (MEA) and a gas diffusion layer (GDL) includes: a plate body stacked on the GDL; stepped portions, on which a reactant gas flows in a first direction, disposed on a first surface of the plate body, the stepped portions disposed in a second direction that intersects the first direction; lands disposed on the stepped portions so as to be spaced apart from one another in the second direction, the lands being in contact with the GDL; first channels defined between the GDL and the stepped portions so as to be disposed between adjacent lands, the reactant gas flowing along the first channels; and second channels defined between the plate body and the GDL so as to communicate with the first channels, the reactant gas flowing along the second channels.
