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 (DAFC) comprising an anode terminal electrically connected to an anode catalyst in fluid communication with a fuel supply; a cathode catalyst in fluid communication with a gaseous oxidant; an electrically conducting cathode plate having a collecting element with evaporation holes, a bendable segment and a terminal site, which collecting element is electrically connected to the cathode catalyst; and a housing containing the collecting element, and a proton exchange membrane (PEM) between the anode catalyst and the cathode catalyst.
(FR)
La présente invention concerne une pile à combustible à alcool direct (DAFC) comprenant une borne d'anode connectée électriquement à un catalyseur d'anode en communication fluidique avec une alimentation en combustible ; un catalyseur de cathode en communication fluidique avec un oxydant gazeux ; une plaque de cathode électroconductrice ayant un élément collecteur pourvu de trous d'évaporation, un segment flexible et un site de borne, lequel élément collecteur est connecté électriquement au catalyseur de cathode ; et un boîtier contenant l'élément collecteur, et une membrane échangeuse de protons (PEM) entre le catalyseur d'anode et le catalyseur de cathode.
