Abstract

L'invention concerne une plaque bipolaire d'une cellule électrochimique, qui est constituée d'une matière synthétique thermodurcissable et thermoplastique et d'une charge de carbone dont la proportion est de préférence comprise entre 70 et 95 % en poids. Ladite plaque bipolaire présente au moins partiellement une structure présentant des éléments tels que des canaux ouverts ou fermés pour diriger ou laisser passer un fluide. Afin d'éviter l'obturation des canaux par exemple par des gouttelettes de fluide, la partie structurée (22) de la plaque bipolaire (12, 14) est formée au moins partiellement hydrophobe ou pourvue d'une couche hydrophobe.
