Title (EN) FUEL CELL
(FR) PILE A COMBUSTIBLE
Abstract:
(EN) A fuel cell (10) includes electrolyte electrode assemblies (26) and a pair of separators (28) sandwiching the electrolyte electrode assemblies (26). Each of the separators (28) is a single plate, and includes a plurality of circular disks (36). First protrusions (48) and second protrusions (52) are provided on both surfaces of the circular disk (36). The first protrusions (48) contact an anode (24) of the electrolyte electrode assembly (26), and the second protrusions (52) contact a cathode (22) of the electrolyte electrode assembly (26). A channel member (56) is provided on a surface of the separator (28) facing the cathode (22). The channel member (56) has a second bridge (60). When a load in a stacking direction is applied to the second bridge (60) of the channel member (56), the second bridge (60) is deformable in the stacking direction.
(FR) L'invention concerne une pile à combustible (10) qui comprend des ensembles électrolyte-électrode (26) et une paire de séparateurs (28) qui prennent en sandwich les ensembles électrolyte-électrode (26). Chaque séparateur (28) est constitué d'une seule plaque et comprend une pluralité de disques (36). Les surfaces de disques (36) comportent des premières protubérances (48) et des secondes protubérances (52). Les premières protubérances (48) sont en contact avec une anode (24) de l'ensemble électrolyte-électrode (26) et les secondes protubérances (52) sont en contact avec une cathode (22) de l'ensemble électrolyte-électrode (26). Une surface du séparateur (28) faisant face à la cathode (22) comprend un élément de voie (56). L'élément de voie (56) comprend un second pont (60). Lorsqu'une charge est appliquée au second pont (60) de l'élément de voie (56), dans la direction de l'empilement, le second pont (60) est déformable dans la direction de l'empilement.
