Title (EN) SOLID ELECTROLYTE MEMBRANE, METHOD AND APPARATUS FOR PRODUCING THE SAME, MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL
(FR) MEMBRANE ELECTROLYTE SOLIDE, PROCEDE ET APPAREIL DE PRODUCTION D'ENSEMBLE ELECTRODE A MEMBRANE, ET PILE A COMBUSTIBLE
Abstract: front page image
(EN)A dope (24) containing a solid electrolyte and an organic solvent is cast onto a web (111) to form a casting membrane (24a). The casting membrane (24a) is contacted with a first liquid (65a). A remaining solvent on the casting membrane (24a) is reduced. The casting membrane (24a) is peeled off as a membrane (62) from a belt (82). In a tenter device (64), the membrane (62) is dried while being stretched. Thereafter, the membrane (62) is contacted with a second liquid (66a). The membrane (62) is transported to a drying chamber (69) and dried while being supported by plural rollers (68). Since the membrane (62) is dried after substituting the first and second liquids (65a) and (66a) for the organic solvent, it becomes easy to evaporate and remove the remaining organic solvent in the membrane (62) together with the first and second liquids (65a) and (66a).
(FR)Un dopant (24) contenant un électrolyte solide et un solvant organique est coulé sur un voile (111) pour former une membrane de coulée (24a) mise en contact avec un premier liquide (65a). Le reliquat de solvant sur la membrane de coulée (24a) subit une réduction. La membrane de coulée (24) est décollée (62) d'une bande (82). Dans un dispositif à rame continue (64), la membrane est séchée tout en étant étirée. La membrane (62 est ensuite mise en contact avec un second liquide (66a), puis passe dans une chambre de séchage (69) ou elle sèche en passant sur plusieurs galets (68). Le solvant organique de la membrane (410) s'évapore en toute sécurité lors de l'évaporation des liquides (65a, 66a). Etant donné que la membrane (62) est mise à sécher après remplacement des deux liquides (65a, 66a) par le solvant organique, il devient facile de faire évaporer et éliminer le restant de solvant organique de la membrane (62) avec ces deux liquides (65a, 66a).
