Fuel cell component and manufacturing device thereof

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.
