Abstract:
1. A fuel cell comprising: a plurality of elementary cells each successively comprising: a plurality of connecting elements configured to connect in series the plurality of elementary cells, a first connecting element of the connecting elements being configured to connect the first assembly of a first elementary cell of the plurality of elementary cells to the second assembly of a second elementary cell of the plurality of elementary cells, the first elementary cell being adjacent to the second elementary cell, wherein: the electrolytic membrane of the first elementary cell has a side wall delineating an empty space with the first connecting element, over a whole thickness of the electrolytic membrane, and a thin barrier layer, formed by a second polymer material, having a water absorption capacity lower than a water absorption capacity of the first polymer material, is interposed between the first connecting element and the electrolytic membrane of the second elementary cell and is in direct contact with the first connecting element and with the electrolytic membrane of the second elementary cell, over a whole thickness of the electrolytic membrane of the second elementary cell.
