Benefits of technology
The present invention provides a way to reduce adhesive costs in fuel cell components. It suggests coating the adhesive only on certain areas between the subgasket and the gas diffusion layer, rather than on the entire subgasket and airtightness being maintained while improving cell performance by preventing the adhesive from damaging the reaction surface. This results in better cost savings and improved performance.
Problems solved by technology
The CCM method has limited productivity for mass production of the fuel cell stack.
However, the bonding force is weak between the catalyst layer and the gas diffusion layer or the subgasket and the gas diffusion layer.
When the keeping (stand-by) duration for mass production of the fuel cell stack is increased the bonding force becomes further weakened.
However, since the interface of the gas diffusion layer that contacts the catalyst layer has a hydrophilic property, the bonding force is not significantly increased.

Abstract
A device for manufacturing a fuel cell component is provided. The device includes a movement device configured to load a gas diffusion layer from a magazine when the gas diffusion layer is loaded to an inlet of a conveyor and unload the gas diffusion layer from an outlet side of the conveyor. An adhesive layer forming device that is disposed over the conveyor forms an adhesive layer in an edge region of the gas diffusion layer. A drying device is configured to dry the adhesive layer formed in the gas diffusion layer. An inspection vision is configured to detect an image of the gas diffusion layer that the adhesive layer is formed. Additionally, a controller operates the movement device, the adhesive layer forming device, and the drying device and configured to use the image to determine a shape of the adhesive layer formed in the gas diffusion layer.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2016-0026657 filed in the Korean Intellectual Property Office on Mar. 4, 2016, the entire contents of which are incorporated herein by reference.BACKGROUND[0002](a) Field of the Invention[0003]The present invention relates to a fuel cell component and a manufacturing device, and more particularly, to coat an adhesive to a portion of a gas diffusion layer and to attach the coated adhesive to a membrane-electrode assembly (MEA) and a subgasket to reduce cost and maintain the position of the adhesive from moving toward an electrode to improve performance.[0004](b) Description of the Related Art[0005]Typically, in a polymer electrolyte fuel cell, a membrane-electrode assembly (MEA) is a main component disposed in the innermost fuel cell. In particular, a 3-layer membrane-electrode assembly (MEA) includes a structure in which catalyst layers for a fuel elect...
