Title (EN) MEMBRANE ELECTRODE ASSEMBLY, PRODUCTION METHOD FOR THE SAME, AND PROTON-EXCHANGE MEMBRANE FUEL CELL
(FR) ENSEMBLE ELECTRODE A MEMBRANE, SON PROCEDE DE PRODUCTION, ET PILE A COMBUSTIBLE A MEMBRANE ECHANGEUSE DE PROTONS
Abstract:
(EN) The membrane electrode assembly of the present invention for the proton-exchange membrane fuel cell includes a polymer electrolyte membrane and an electrode catalyst layer, wherein at least a part of the polymer electrolyte membrane infiltrates into the electrode catalyst layer, and wherein the polymer electrolyte membrane is formed by polymerizing a composition containing at least a compound having proton conductivity and a compound having activity to an active energy ray, or a composition containing at least a compound having proton conductivity and activity to the active energy ray. The object of the present invention is to provide a membrane electrolyte assembly for realizing a high-output proton-exchange membrane fuel cell by improving a bonding state between the polymer electrolyte membrane and the electrode catalyst layer to reduce an internal resistance, and by providing a three-dimensional three-phase interface to increase reaction areas.
(FR) L'invention concerne un ensemble électrode à membrane pour pile à combustible à membrane échangeuse de protons, qui comporte une membrane à électrolyte polymère et une couche de catalyseur électrode. Au moins une partie de la membrane à électrolyte polymère infiltre la couche de catalyseur électrode, et la membrane à électrolyte polymère est formée par polymérisation d'une composition contenant au moins un composé à conductivité protonique et un composé à activité à un rayonnement d'énergie active, ou une composition contenant au moins un composé à conductivité protonique et une activité au rayonnement d'énergie active. L'invention concerne la fourniture d'un ensemble d'électrolyte à membrane pour réaliser une pile à combustible à membrane échangeuse de protons à rendement élevé par amélioration d'un état de liaison entre la membrane à électrolyte polymère et la couche de catalyseur électrode afin de réduire une résistance interne, et par fourniture d'une interface à trois phases tridimensionnelle pour accroître les zones de réaction.
