Title
(EN) SYSTEM FOR REFUELLING A HEARING AID FUEL CELL
(FR) SYSTÈME DE RECHARGEMENT D'UNE PILE À COMBUSTIBLE DE PROTHÈSE AUDITIVE
Abstract
(EN)
The invention relates to a system for refuelling a fuel cell having a fuel reservoir, the system comprising a cartridge (1) having a first reservoir (2) for storing fuel for the fuel cell, a refuelling unit adapted to receive a waste liquid from the fuel reservoir of the fuel cell and provide fuel from the first reservoir (2) of the cartridge (1) to the fuel reservoir of the fuel cell, wherein the system further comprises a second reservoir for storing the waste liquid from the fuel cell, a cartridge for use with the system, a refuelling unit for use with the system, and a method of reguelling a fuel cell having a fuel reservoir.
(FR)
L'invention concerne un système de rechargement d'une pile à combustible comportant un réservoir de combustible, le système comprenant une cartouche (1) ayant un premier réservoir (2) pour stocker du combustible pour la pile à combustible, une unité de rechargement conçue pour recevoir un liquide résiduaire provenant du réservoir de combustible de la pile à combustible et fournir du combustible à partir du premier réservoir (2) de la cartouche (1) jusqu'au réservoir de combustible de la pile à combustible, le système comprenant en outre un second réservoir destiné à stocker le liquide résiduaire provenant de la pile à combustible, une cartouche destinée à être utilisée avec le système, une unité de rechargement destinée à être utilisée avec le système, et un procédé de régulation d'une pile à combustible ayant un réservoir de combustible.
