Abstract

Pile à combustible, notamment du type à membrane échangeuse de protons, comprenant un empilement (2) de cellules élémentaires, l'empilement (2) étant pris en sandwich entre au moins deux plaques (3) de serrage pour appliquer une pression de serrage déterminée sur l'empilement (1), au moins une première extrémité de l'empilement (2) comprenant un organe (4, 5) collecteur de courant conducteur de l'électricité reliée électriquement aux cellules de l'empilement (2), pour collecter la somme des courants électriques produits par les cellules de l’empilement (2), caractérisé en ce que la plaque (3) de serrage d’une première extrémité de l’empilement (2) est composée d’un matériau conducteur de l’électricité et comprend une face (4) de contact conductrice en contact avec l’empilement (2) de cellule pour collecter la somme des courants électriques produits par les cellules, ladite plaque (3) comprenant sur sa périphérie une borne (5) de collecte du courant collectée par la face (4) de contact conductrice, ladite borne (5) étant en matériau conducteur électrique et en contact électrique avec ladite plaque (3) et en ce qu’au moins une partie du reste de la surface périphérique de ladite plaque (3) de serrage de la première extrémité est revêtue d’une couche (6) d’isolant électrique.
