Development of a laser-based glass sealing joining process for the fuel cell manufacturing

In the Central Technology Division of Forschungszentrum Jülich GmbH procedures and manufacturing concepts used in production of stationary and mobile fuel cell stacks on the basis of the material developments of the involved research institutes are developed. From essential meaning is the application of self developed glass sealing materials as joining and isolation medium. The use of glass sealing material is up to now limited on the furnace technology with low heating and cooling rates. The potentials of the laser as adaptable tool for manufacturing and repair of the fuel cell stacks should be evaluated within the scope of this research study.
