Title
(EN) PROCESS OF MANUFACTURING A MEMBRANE ELECTRODE ASSEMBLY
(FR) PROCÉDÉ DE FABRICATION D'UN ASSEMBLAGE MEMBRANE-ÉLECTRODES
Abstract
(EN) The present invention provides a process of manufacturing a sub-gasketed membrane electrode assembly in which ultrasonic energy is applied to a single face of an intermediate construct to form bonds between the gas diffusion layers and the sub-gaskets.
(FR) La présente invention concerne un procédé de fabrication d'un assemblage membrane-électrodes à sous-joints dans lequel de l'énergie ultrasonore est appliquée à une seule face d'une construction intermédiaire pour former des liaisons entre les couches de diffusion de gaz et les sous-joints.
