CA 2451787

A membrane/electrode coupling trimming apparatus comprising a trimming lower die for mounting a membrane/electrode coupling, a trimming upper die equipped with a trimming blade, and a holding member so suspended as to elevate in this trimming upper die and chuck a carbon electrode. Another disclosure is a membrane/electrode coupling carrier apparatus including a holding member that chucks the carbon electrode and so holds it as to prevent its slide. The positioning and fixture of the membrane/electrode coupling during trimming and trimming reliability enhance to prevent the positional slide of a trimmed membrane/electrode coupling during its transportation, so that the performance of a fuel cell improves.

La présente invention concerne un appareil (10) d'ajustage d'un ensemble membrane/électrode qui comprend un outil d'ajustage inférieur (14) servant à retenir un ensemble (65) membrane/électrode, un outil d'ajustage supérieur (16) équipé d'une lame d'ajustage (15) et un élément (17) de support suspendu de manière à élever une électrode en carbone (12) dans l'outil d'ajustage supérieur et le mandrin. Cette invention concerne également un appareil (72) de support pour l'ensemble membrane/électrode qui comprend un élément de support qui retient l'électrode en carbone et l'empêche ainsi de glisser. Le positionnement et la fixation de cet ensemble membrane/électrode pendant l'ajustage et la fiabilité de l'ajustage empêchent l'ensemble membrane/électrode ajusté de glisser pendant son transport, de sorte que le fonctionnement et la qualité d'une pile à combustible sont améliorés.
