SEPARATOR FOR FUEL CELL AND ITS MANUFACTURING METHOD AND FUEL CELL STACK USING THE SEPARATOR

摘要

A separator for a fuel cell, capable of using both sides, its manufacturing method and a fuel cell stack employing a separator are provided to obtain an economic fuel cell stack which is advantageous for miniaturization and facilitates the manufacture by using a separator for a fuel cell capable of using both sides. A separator for a fuel cell consists of a single plate. The single plate comprises a side installed with a first flow channel(110) by a negative part of wound shape; a first inlet hole(110a) for the inflow of the fluid which is connected to one end of the first flow channel; a first outlet hole(110b) for the inflow of the fluid which is connected to the other end of the first flow channel; a second flow channel(110) by the other negative part of wound shape; the other side facing the one side; a second inlet hole(120a) for the inflow of the fluid which is connected to one end of the second flow channel; and a second outlet hole(110b) for the inflow of the fluid which is connected to the other end of the second flow channel.
