A fuel cell includes an electrolyte electrode assembly and separators. The separator includes first through third plates which are stacked together. A fuel gas channel connected to a fuel gas supply passage is formed between the first and third plates. The fuel gas channel forms a fuel gas pressure chamber between the first and third circular disks. Further, an oxygen-containing gas channel connected to an oxygen-containing gas supply passage is formed between the second and third plates. The oxygen-containing gas channel forms an oxygen-containing gas pressure chamber between the second and third circular disks.
L'invention concerne une pile à combustible (10) comprenant un ensemble electrolyte electrode (26) et des séparateurs (28). Le séparateur (28) comprend de une à trois plaques (30, 32, 34) empilées. Un canal de gaz combustible (76), connecté à un passage d'alimentation en gaz combustible (36), est formé entre la première et la troisième plaque (30, 34). Le canal de gaz combustible (76) forme entre le premier et le troisième disque circulaire (42, 70) une chambre de pression (86) destinée au gaz combustible. En outre, un canal de gaz oxygéné (84) qui est connecté à un passage d'alimentation en gaz oxygéné (50), est formé entre la deuxième et la troisième plaque (32, 34). Le canal de gaz oxygéné (84) forme entre le deuxième et le troisième disque circulaire (56, 70) une chambre de pression (88) destinée au gaz oxygéné (88).
