Title
(EN) SOLID POLYMER TYPE FUEL CELL AND PRODUCTION METHOD THEREOF
(FR) PILE A COMBUSTIBLE DE TYPE POLYMERE SOLIDE ET PROCEDE DE PRODUCTION DE CETTE DERNIERE
Abstract
(EN)
A solid polyelectrolyte fuel cell comprising catalyst layers disposed on the opposite faces of a solid polyelectrolyte consisting of ion exchange membranes, and collectors disposed on the outer sides of the layers, wherein the collectors are allowed to contain solvent-soluble fluorine-containing polymer (preferably, polymer having a fluorine-containing aliphatic ring structure) having substantially no ion exchange group, whereby the collectors can have a high water repellence for an extended period, and the fuel cell can operate with a high, stable output efficiency for an extended period.
(FR)
L'invention concerne une pile à combustible de polyélectrolyte solide comprenant des couches de catalyseur placées sur les faces situées en regard d'un polyélectrolyte solide se composant de membranes échangeuses d'ions. Cette pile comprend également des collecteurs placés sur les côtés extérieurs des couches, qui peuvent contenir un polymère à base de fluor soluble dans un solvant (de préférence, un polymère comportant une structure de chaîne aliphatique à base de fluor) ne présentant sensiblement aucun groupe échangeur d'ions. Ces collecteurs peuvent avoir des propriétés de résistance à l'eau élevée pendant un laps de temps prolongé, et la pile à combustible peut fonctionner avec une efficacité de sortie stable et élevée pendant une grande période.
