(EN) CELL STRUCTURE OF FUEL CELL
(FR) STRUCTURE DE CELLULE DE PILE À COMBUSTIBLE
(JA) 燃料電池のセル構造
Abstract
(EN)
A cell structure of a fuel cell, which is provided with: a membrane electrode assembly (M) wherein an electrolyte membrane (1) is held between a pair of electrode layers (2, 3); a frame (4) that is arranged on the outer peripheral portion of the electrolyte membrane (1); a separator (5) that forms a gas channel (G) between itself and the membrane electrode assembly (M); a sealing member (6) that is arranged closer to the outer periphery than the gas channel (G); and a porous metal body (23) that has gas permeability and is arranged on the surfaces of the electrode layers (2, 3). The porous metal body (23) is provided, on the outer periphery thereof, with an extending portion (23A) that extends beyond the electrode layer (2). The frame (4) is provided with an embedding portion (40) in which the extending portion (23A) of the porous metal body (23) is embedded. A holding means, which holds the extending portion (23A) of the porous metal body (23), is provided between the separator (5) and the embedding portion (40).

L'invention concerne la structure de cellule d'une pile à combustible, qui comprend : un ensemble d'électrode à membrane (M), dans lequel une membrane d'électrolyte (1) est maintenue entre une paire de couches électrodes (2, 3) ; une armature (4) qui est agencée sur la partie périphérique extérieure de la membrane d'électrolyte (1) ; un séparateur (5) qui forme un canal gazeux (G) entre lui-même et l'ensemble d'électrode à membrane (M) ; un élément d'étanchéité (6) agencé de façon à être plus proche de la périphérie extérieure que du canal gazeux (G) ; et un corps métallique poreux (23) qui est perméable aux gaz et qui est agencé sur les surfaces des couches électrodes (2, 3). Le corps métallique poreux (23) comprend, sur sa périphérie extérieure, une partie d'extension (23A) qui s'étend au-delà de la couche électrode (2). L'armature (4) comprend une partie enrobante (40) dans laquelle la partie d'extension (23A) du corps métallique poreux (23) est enrobée. Un moyen de maintien, qui maintient la partie d'extension (23A) du corps métallique poreux (23), est disposé entre le séparateur (5) et la partie d'enrobage (40).
