Title
(EN) A DIRECT ALCOHOL FUEL CELL
(FR) PILE À COMBUSTIBLE À ALCOOL DIRECT
Abstract
(EN)
The present invention relates to a direct alcohol fuel cell comprising a housing containing a proton exchange membrane (PEM) separating an anode section from a cathode section, which anode section and which cathode section are contained in the housing, the cathode section comprising a cathode collection element having one or more ventilation holes, which cathode collection element is electrically connected to a cathode catalyst, which cathode catalyst is in diffusive communication with a gaseous oxidant, and the anode section comprising an anode collection element electrically connected to an anode catalyst, the DAFC comprising an oleophobic filter covering the ventilation hole(s). The oleophobic filter may be held in place using any appropriate means as desired. The fuel cell is suited for a microelectronic device.
(FR)
La présente invention porte sur une pile à combustible à alcool direct comprenant un logement contenant une membrane d’échange de protons (PEM) séparant une section d’anode d’une section de cathode, laquelle section d’anode et laquelle section de cathode étant contenues dans le logement, la section de cathode comprenant un élément de collecte de cathode ayant un ou plusieurs trous d’aération, lequel élément de collecte de cathode étant connecté électriquement à un catalyseur de cathode, lequel catalyseur de cathode est en communication diffusive avec un oxyde gazeux, et la section d'anode comprenant un élément de collecte d’anode connecté électriquement à un catalyseur d’anode, la DAFC comprenant un filtre oléophobe recouvrant le ou les trous d’aération. Le filtre oléophobe peut être maintenu en place au moyen de tout moyen approprié comme on le désire. La pile à combustible convient à un dispositif microélectronique.
