The invention relates to the technical field of electrochemistry, and especially to a method and a device for producing fuel cell components, especially membrane-electrode units ( MEE") for membrane fuel cells. According to the inventive method, anode or cathode electrodes are first applied to two adjacent heated rolls subjected to a vacuum. The applied vacuum enables the electrodes to be introduced into a roll gap in a precisely positioned manner and then laminated with an ion-conductive membrane. The inventive method enables high production speeds to be achieved as a result of the extended heat-affected zone. The inventive device consists of a roll press with heatable vacuum rolls, and is advantageous as a result of the simple structure and the lack of transfer points. |
