PURPOSE: A separator for a fuel cell, a manufacturing method thereof, and a fuel cell stack including thereof are provided to improve the efficiency of the fuel cell by smoothly discharging water generated from a membrane-electrode assembly to the outside the separator. CONSTITUTION: A separator(14) for a fuel cell comprises the following: a plate-shaped main body in a plate form; a channel to supply fuel and oxygen to a membrane-electrode assembly(12); and an ultra-hydrophobic polymer layer including plural protrusions on the surface, installed on the channel. A manufacturing method of the separator includes the following steps: forming the channel on the main body; producing the ultra-hydrophobic polymer layer; and attaching the ultra-hydrophobic polymer layer on the channel. |
