BIPOLAR PLATE OF FUEL CELL

摘要

PURPOSE: A fuel cell separator is provided to reduce warpage during molding the fuel cell separator such as press molding. CONSTITUTION: A fuel cell separator comprises a frame with a reaction channel; and a warpage reducing unit(200) which reduces warpage phenomenon during molding the reaction channel. The warpage reducing unit is provided to prevent leakage of operation fluid from the frame and is located in the peripheral part of a gasket dam. The warpage reducing unit is provided to a warpage reducing line(210) along the circumference of the gasket dam and has a plurality of unit patterns(230) with a constant interval.
