Title
(EN) FUEL CELL STACK
(FR) EMPILEMENT DE PILE À COMBUSTIBLE
(JA) 燃料電池スタック
Abstract
(EN)
Provided is a fuel cell stack (FS) in which a unit cell (C) is formed by holding a membrane electrode assembly (1) in a sandwiched state between a pair of separators (2, 2) having depression parts (2B) and protrusion parts (2A), and the fuel cell stack (FS) is formed by stacking the unit cells (C). Coolant fluid flow-through spaces (F) are formed between the unit cells (2, 2). Displacement absorption members (10) are positioned in the flow-through spaces (F) which absorb a displacement between the unit cells (C). The displacement absorption members (10) have a configuration further comprising spring function units (10B) having free ends (J) and fixed ends (K), and further comprising intrusion prevention means (2A, 5) which prevent the free ends (J) of the spring function parts (10B) from intruding into the depression parts (2A). While favorably maintaining a displacement absorption function between the unit cells (C), miniaturization is implemented.

L'invention concerne un empilement de pile à combustible (FS) dans lequel une cellule individuelle (C) est formée en maintenant un ensemble électrode-membrane (1) dans un état de prise en sandwich entre une paire de séparateurs (2, 2) ayant des parties en dépression (2B) et des parties en saillie (2A), et l'empilement de pile à combustible (FS) est formé par empilement des cellules individuelles (C). Des espaces d'écoulement traversants d'un fluide de refroidissement (F) sont formés entre les cellules individuelles (2, 2). Des éléments d'absorption de déplacement (10) sont implantés dans les espaces d'écoulement traversants (F) pour absorber un déplacement entre les cellules individuelles (C). Les éléments d'absorption de déplacement (10) ont une configuration qui comprend en outre des unités fonctionnelles de ressort (10B) qui possèdent des extrémités libres (J) et comprend en outre des extrémités fixes (K) et des moyens de prévention de pénétration (2A, 5) qui empêchent les extrémités libres (J) des unités fonctionnelles de ressort (10B) de pénétrer dans les parties en dépression (2A). Une miniaturisation est mise en œuvre tout en maintenant de manière favorable une fonction d'absorption de déplacement entre les cellules individuelles (C).
