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 proton exchange membrane (PEM) separating an anode section from a cathode section, which cathode section contains a cathode collection element electrically connected to a cathode catalyst, the cathode catalyst being in diffusive communication with a gaseous oxidant, and which anode section comprises an anode collection element electrically connected to an anode catalyst, the anode catalyst being in diffusive communication with a fuel supply, wherein the PEM is structured to have a bottom and walls extending from the bottom to a containment distance into the cathode section, and wherein the cathode catalyst is located within the containment distance from the bottom. The fuel cell is suited for a microelectronic device.

La présente invention concerne une pile à combustible à alcool direct comprenant une membrane échangeuse de protons (PEM) séparant une section d'anode d'une section de cathode, ladite section de cathode contenant un élément de collecte de cathode connecté électriquement à un catalyseur de cathode, le catalyseur de cathode étant en communication de diffusion avec un oxydant gazeux, et laquelle section d'anode comprend un élément de collecte d'anode connecté électriquement à un catalyseur d'anode, le catalyseur d'anode étant en communication de diffusion avec une alimentation en combustible, le PEM étant structuré pour avoir un fond et des parois s'étendant depuis le fond jusqu'à une distance de confinement dans la section de cathode, et le catalyseur de cathode étant situé à l'intérieur de la distance de confinement à partir du fond. La pile à combustible est appropriée pour un dispositif microélectronique.
