Abstract

Plaque bipolaire (1) pour la réalisation d'un empilement d'une pile à combustible, ladite plaque bipolaire (1) comprenant des canaux de circulation pour un premier et un second réactif de pile à combustible (A, B), ainsi que pour un fluide caloporteur (C), les canaux de circulation (A, B, C) s'étendant selon une direction longitudinale de la plaque (1), de sorte que chaque canal de circulation pour un réactif (A, B) soit encadré par deux canaux de circulation de fluide caloporteur (C), les canaux de circulation (A, B, C) étant configurés de manière à générer des pertes de charges variables selon la position du canal selon la direction transversale de la plaque (1), de manière à établir un débit homogène de réactifs (A, B) sur l'ensemble de la plaque (1), et un débit homogène de fluide caloporteur (C) sur l'ensemble de la plaque (1).
