Abstract: front page image
(EN)Disclosed is a membrane-electrode assembly (10) comprising a proton conductive electrolyte membrane (11) and a first electrode (12) bonded to the electrolyte membrane. The first electrode contains a catalyst (121, 122) and a first ionomer (123) covering the catalyst and having a proton exchange function. This membrane-electrode assembly (10) is characterized in that the value of [generated water (mol/min)]/[volume of first ionomer (cm3)] at a rated output point of the membrane-electrode assembly is not less than 1350 in the first electrode.
(FR)La présente invention concerne un ensemble membrane- électrode (10) comprenant une membrane électrolyte conductrice de proton (11) et une première électrode (12) liée à la membrane électrolyte. La première électrode contient un catalyseur (121, 122) et un premier ionomère (123) recouvrant le catalyseur et ayant une fonction d'échange de proton. Cet ensemble de membrane- électrode (10) est caractérisé en ce que la valeur de [eau générée (mol/min)]/[volume de premier ionomère (cm3)] à un point de sortie nominal de l'ensemble de membrane- électrode n'est pas inférieure à 1350 dans la première électrode.
(JA) 膜−電極接合体(10)は、プロトン伝導性を有する電解質膜(11)と電解質膜上に接合された第1電極(12)とを備える膜−電極接合体であって、第1電極は、触媒(121,122)と、触媒を被覆しプロトン交換機能を有する第1アイオノマ(123)とを含み、第1電極において、膜−電極接合体の定格出力点における生成水量(mol/min)/第1アイオノマ体積(cm)は、1350以上であることを特徴とする。
