PURPOSE: A separator for fuel cell is provided to prevent the reaction gas clogging of channels due to the localized ice blocking phenomenon of a channel plate at temperature under melting point, thereby improving cool starting property of a vehicle. CONSTITUTION: A separator for fuel cell(100) comprises: a first channel plate(10) in which channels(11) supplying fuel to a membrane-electrode assembly are formed; a second channel plate, in which channels supplying oxidizer to the membrane-electrode assembly are formed; coolant flow channels between the first and the second channel plate; and at least one bypass flow channel(50), which connects the channels, formed in the first or the second channel plate. |
