Abstract: front page image
(EN)Catalytic electrodes for fuel cell (102, 108) comprise conductive substrates (104, 110) and, superimposed on the substrates (104, 110), catalyst layers (106, 112). These catalyst layers (106, 112) comprise carbon particles (401) bearing catalytic substance (405) which have an average particle diameter of given range and solid polymeric electrolyte material (403) mixed with the carbon particles (401). These carbon particles (401) comprise carbon nanohorn aggregate (401) composed of multiple carbon nanohorns (407) aggregated spherically. This carbon nanohorn aggregate (407) bears the above catalytic substance (405).
(FR)Cette invention concerne des électrodes catalytiques pour pile à combustible (102, 108) comprenant des substrats conducteurs (104, 110) ainsi que des couches de catalyseur (106, 112) superposées sur lesdits substrats (104, 110). Ces couches de catalyseur (106, 112) comprennent des particules de carbone (401) porteuses d'une substance catalytique (405) présentant un diamètre moyen des particules compris dans une gamme donnée ainsi qu'un matériau électrolytique polymère solide (403) mélangé aux particules de carbone (401). Ces particules de carbone (401) comprennent un agrégat de nanocornes de carbone (401) composé de multiples nanocornes (407) de carbone qui sont agrégées de manière sphérique. Cet agrégat de nanocornes (407) de carbone porte la substance catalytique (405) susmentionnée.
(JA) 燃料電池用触媒電極(102、108)は、導電性を有する基体(104、110)と、前記基体(104、110)上に設けられた触媒層(106、112)とを具備する。前記触媒層(106、112)は、所定の範囲の平均粒径を有する触媒物質(405)を担持する炭素粒子(401)と、前記炭素粒子(401)と混合された固体高分子電解質材(403)とを備える。前記炭素粒子(401)は、複数のカーボンナノホーン(407)が球状に集合したカーボンナノホーン集合体(401)を含む。前記カーボンナノホーン集合体(401)は、前記触媒物質(405)が担持されている。
