Abstract

Official abstract text for this publication.

A bonding jig used for bonding a gas diffusion layer or a fuel cell constituent member including the gas diffusion layer to be sandwiched between separators and an adhesive sheet for joining the separators to the gas diffusion layer or fuel cell constituent member, the bonding jig being capable of simultaneously performing bonding and eliminating fluffy fibers on the gas diffusion layer. The bonding jig includes a loading area (recess) where the gas diffusion layer is loaded when the bonding is performed, and the recess has a plurality of communication holes that communicate with the outside and that are coupled to a suction pump. While the adhesive sheet is placed on the side of the upper face of the bonding jig so as to be integrated with the gas diffusion layer, the suction pump is actuated to eliminate fluffy fibers on the gas diffusion layer.

First claim

Opening claim text (preview).

What is claimed is: 1 . A bonding jig used for bonding a gas diffusion layer or a fuel cell constituent member including the gas diffusion layer to be sandwiched between separators and an adhesive sheet for joining the separators to the gas diffusion layer or the fuel cell constituent member, the bonding jig comprising: a loading area where the gas diffusion layer is loaded when the bonding is performed, the loading area having at least on its periphery a plurality of communication holes communicating with an outside, the communication holes being coupled to a suction device. 2 . The bonding jig according to claim 1 , wherein the loading area has an appropriate number of grooves, each groove having the communication holes that open on a bottom face of the groove.
