SEPERATOR FOR FUEL CELL, FUEL CELL SYSTEM HAVING THE SAMES AND FUEL CELL STACK

摘要

A separator for a fuel cell, a fuel cell system containing the separator, and a stack for a fuel cell system containing the separator are provided to improve cooling efficiency by controlling the inflow amount of cooling water and to decrease a manufacturing time and a manufacturing cost by forming a cooling water in/outlet by stamping method. A separator(1) for a fuel cell comprises a reaction gas inflow aperture(11) which is formed at the one part of a separator; a reaction gas outflow aperture which is formed at the opposite part of the separator; a cooling water inflow aperture(12) which is formed at the one part of the separator; a cooling water outlet aperture which is formed at the opposite part of the separator; a first channel(21) which is formed at one surface of the separator to allow a reaction gas to flow; a second channel(31) which is formed at the other surface of the separator to allow cooling water to flow; and a cooling water inlet/outlet(32) which connects the second channels each other to allow cooling water to flow through the second channel. Preferably the first and second channels have a serpentine structure.
