Abstract | The present invention improves the handling properties of a rubber-only gasket and the affixability thereof to an attachment position. To this end, the provided gasket is: obtained by combining a gasket body of the rubber-only type, and a carrier sheet that comprises a resin film and holds the gasket body in an un-adhered state; and characterized in that the gasket body is provided with an adhesive section or bonding section for adhering or bonding the gasket body to an attachment position when attaching the gasket body to the attachment position. The adhesive section or bonding section is prepared by providing the lateral surface of the gasket body with a projecting section, and coating the surface of the projecting section with an adhesive or bonding agent. The gasket body is to be used as a gasket for a fuel cell to be incorporated into a fuel cell stack.
L'invention concerne une amélioration des propriétés de manipulation d'un joint d'étanchéité tout caoutchouc et sa capacité de fixation au niveau d'une position de fixation. À cet effet, le joint d'étanchéité proposé est : obtenu par combinaison d'un corps de joint d'étanchéité du type tout caoutchouc et d'une feuille de support qui comprend un film en résine et maintient le corps de joint d'étanchéité dans un état non collé; et caractérisé en ce que le corps de joint d'étanchéité est pourvu d'une section adhésive ou section de liaison destinée à faire adhérer ou à lier le corps de joint d'étanchéité à une position de fixation lors de la fixation du corps de joint d'étanchéité à la position de fixation. La section adhésive ou section de liaison est préparée par la fourniture à la surface latérale du corps de joint d'étanchéité d'une section en saillie et par le revêtement de la surface de la section en saillie avec un agent adhésif ou agent de liaison. Le corps de joint d'étanchéité est à utiliser sous la forme d'un joint d'étanchéité pour pile à combustible incorporée dans un empilement de piles à combustible. |
