BIPOLAR PLATES FOR FUEL CELL AND FUEL CELL COMPRISING SAME

摘要

The invention concerns a bipolar plate (7) for fuel cell comprising on at least one of its surfaces at least one groove (15) capable of forming with the surface of an adjacent electrode (13) at least a gas feeding channel, wherein said feeder channel has a form or shape such that it enables to move the liquid away from the diphasic flow circulating in said channel of said electrode surface. The invention also concerns a method for preparing such a bipolar plate and a fuel cell comprising at least one of said bipolar plates.
