Problems solved by technology

Although this joining method can meet the requirement of reducing the volume, the colloid of the adhesive tends to overflow into the flow channel, blocking the flow of fuel or products in the flow channel, thereby affecting the power generation effect of the fuel cell. Therefore, the fuel cell adopts the joining method. There is still room for improvement in the implementation, in order to prevent the colloid of the next layer from overflowing into the flow channel

Abstract

The invention relates to a package assembly for a runner plate and a bonding layer of a fuel battery, which comprises the runner plate and the bonding layer, wherein the runner plate comprises a plate body, and the plate body is provided with a plurality of runners which are concave from the surface to the inside; the bonding layer is made of a one-off hardening adhesive, provided with at least one prehardened area, and adhered to the plate body; and the prehardened areas cover a part of the runners.

Description

technical field [0001] The invention relates to an assembly structure of a flow channel plate and an adhesive layer for a fuel cell, especially when the flow channel plate and an adhesive layer are assembled, a part of the area can be covered by the pre-hardened area formed by the adhesive layer These flow channels are designed to prevent the adhesive of the next layer from overflowing to the flow channels covered by the hardened areas. Background technique [0002] In the traditional fuel cell structure, the two plates are generally combined by screwing, for example, the flow channel plate and the collector plate are screwed together, and the flow channel plate and the collector plate are screwed together by bolts and nuts. together. Although the screwing method is quite simple and easy to implement, the volume of the manufactured bipolar plate cannot meet the requirement of miniaturization. [0003] Therefore, in order to reduce the volume, an adhesive bonding method is ...
