Abstract: front page image
(EN)It is aimed to provide a thinner electrolyte layer while suppressing occurrence of cracks in the electrolyte layer. An inorganic dense electrolyte layer (36) is provided together with a dense base (31), thereby forming an electrolyte membrane (30). A fuel cell stack is formed by stacking a plurality of cells in series which cells are respectively composed of the electrolyte membrane (30), a fuel electrode and an oxygen electrode.
(FR)L'invention concerne une méthode permettant d'obtenir une couche d'électrolyte mince, tout en supprimant l'apparition de fissures dans cette couche d'électrolyte. Une couche d'électrolyte dense inorganique (36) est prévue, conjointement à une base dense (31), ce qui permet de former une membrane électrolytique (30). Un empilement de piles à combustible est formé par l'empilement d'une pluralité de piles, en série, ces piles étant respectivement constituées de la membrane électrolytique (30), d'une électrode à combustible et d'une électrode à oxygène.
(JA) 電解質層にクラックが発生するのを抑制しながら電解質層の薄膜化を図る。無機質の緻密な電解質層36を、緻密な基材31とともに設けることにより電解質膜30を形成する。電解質膜30と燃料極と酸素極とから構成されるセルを直列に複数積層して燃料電池スタックを構成する。
