A method of setting a cutting time of a gasket during manufacture of a membrane electrode assembly (MEA) is provided. The method includes: moving a reaction sheet, in which electrode layers are formed on an electrolyte membrane with a predetermined interval; photographing a boundary area between the electrolyte membrane and the electrode layer in the moving reaction sheet by using a fixed vision; setting a front end reference line and a rear end reference line between a front-most end and a rear-most end in the boundary area; calculating a trigger reference line between the front end reference line and the rear end reference line, except for a front portion of the front end reference line and a rear portion of the rear end reference line; and calculating a cutting time of a gasket based on the trigger reference line.

A GDL cutting system of a fuel cell includes: a laser-cutting device that forms a gas diffusion layer by radiating a laser on the surface of a GDL fabric panel moving on a conveyer; an adsorbing-conveying device that adsorbs and conveys at least two gas diffusion layers cut by the laser-cutting device; a first vision sensor that senses an upper side of the gas diffusion layers cut by the laser-cutting device; and a second vision sensor that senses a lower side of the gas diffusion layers adsorbed and conveyed by the adsorbing-conveying device.
