Abstract
Fuel cell comprising a stack of bipolar plates (1) and polymer films (2), in which the polymer films comprise a lip (3) that overhangs on all sides relative to the adjacent bipolar plates (1).
Claims9
A fuel cell comprising a stack of fluid distribution plates and polymer films comprising a zone that forms an ion-exchange membrane, each polymer film being interposed between two fluid distribution plates in order to form an individual cell, wherein at least one individual cell comprises an overhanging lip made of an electrically non-conductive material, which overhangs relative to at least one end of the adjacent fluid distribution plates, wherein each lip overhangs relative to the adjacent distribution plates by a length “d” greater than the thickness “e” of the adjacent fluid distribution plates, and wherein each lip is configured so it can be bent over the entire thickness “e” of one of said adjacent fluid distribution plates.
