In a polymer electrolyte fuel cell wherein a plurality of unit cells are arranged in a flat manner oriented in the same direction, and the prescribed adjacent unit cells are electrically connected in series so as to connect the plurality of unit cells in series, a flat-type polymer electrolyte fuel cell is made possible by providing at least one of a through hole connecting portion, a filled via connecting portion and a bump connecting portion in an insulating portion located between the prescribed adjacent unit cells, electrically insulated from the unit cells and having a thickness approximately equal to that of the unit cell, for establishing electrical connection between the prescribed adjacent unit cells.
L'invention concerne une pile à combustible à polyélectrolyte, comprenant une pluralité de cellules unitaires montées en série. On forme cette pile en disposant les cellules unitaires orientées dans une même direction selon une configuration planaire, les cellules unitaires adjacents particulières étant connectées électriquement en série les unes avec les autres. L'élément isolant est formé d'au moins un élément de connexion comprenant une ouverture traversante, un élément de connexion comprenant des trous d'interconnexion à remplissage et un élément de connexion à bosses. Cet élément isolant est disposé entre les éléments unitaires adjacents particuliers, et isolé électriquement de chaque élément unitaire. L'élément isolant est presque aussi large qu'une cellule unitaire. On obtient ainsi une pile à combustible à polyélectrolite plane.
