Abstract
(EN) Provided is an anode support body for a solid oxide fuel cell, the anode support body exhibiting high porosity and sufficient mechanical strength. Also provided is an anode supported-type solid oxide fuel cell single cell. An anode support body for a solid oxide fuel cell, the anode support body having a paper-like porous support base body formed by molding ion conductive oxide fibers into the shape of a non-woven cloth, and an anode active layer configured from electrode catalyst particles and ion conductive oxide particles, wherein at least a portion of the anode active layer is formed in the interior of the paper-like porous support base body. An anode supported-type solid oxide fuel cell single cell provided with the aforementioned anode support body exhibits excellent power generation performance because the anode support body has extremely large porosity (voids) and pore size, and not only because the three-phase boundary where electrode reaction occurs is spread in three dimensions in a network formed by the ion conductive oxide fibers, but also because the thickness of the three-phase boundary spreading within the network (the thickness from the surface of the ion conductive oxide) can be maintained thin.
(FR) L'invention concerne un corps de support d'anode pour une pile à combustible à oxyde solide, le corps de support d'anode présentant une porosité élevée et une résistance mécanique suffisante. L'invention concerne également une cellule unique de pile à combustible à oxyde solide de type supportée par anode. L'invention concerne un corps de support d'anode pour une pile à combustible à oxyde solide, le corps de support d'anode ayant un corps de base de support poreux de type papier formé par moulage de fibres d'oxyde conducteur ionique selon la forme d'un tissu non tissé, et une couche active d'anode configurée à partir de particules de catalyseur d'électrode et de particules d'oxyde conducteur ionique, au moins une partie de la couche active d'anode étant formée dans l'intérieur du corps de base de support poreux de type papier. Une cellule unique de pile à combustible à oxyde solide de type supporté par anode comprenant le corps de support d'anode susmentionné présente une excellente performance de génération d'électricité car le corps de support d'anode possède une porosité (lacunes) et une taille de pore extrêmement grandes, et non seulement car la frontière triphasique où la réaction de d'électrode se produit est diffusée dans les trois dimensions dans un réseau formé par les fibres d'oxyde conducteur ionique, mais également car l'épaisseur de la frontière triphasique se diffusant dans le réseau (l'épaisseur à partir de la surface de l'oxyde conducteur ionique) peut être maintenue fine.
(JA)  十分な機械的強度を維持しつつ、高い気孔率を有する固体酸化物形燃料電池用アノード支持体及び該アノード支持型固体酸化物形燃料電池単セルを提供する。イオン伝導性酸化物繊維を不織布状に成形してなるペーパー状多孔質支持基体と、電極触媒粒子及びイオン伝導性酸化物粒子で構成されるアノード活性層とを有し、前記アノード活性層の少なくとも一部が、前記ペーパー状多孔質支持基体の内部に形成されてなる固体酸化物形燃料電池用アノード支持体。該アノード支持体を備えたアノード支持型固体酸化物形燃料電池単セルは、アノード支持体の細孔径、気孔率(空隙率)が非常に大きく、電極反応の起こる三相界面がイオン伝導性酸化物繊維がなすネットワーク上に三次元的に広がっているだけでなく、ネットワーク内に広がる三相界面厚さ(イオン伝導性酸化物表面からの厚さ)を薄く保つことができるため、優れた発電性能を示す。
