The fuel cell is increasingly a key position in energy supply of the future. In the Central Technology Division of the Forschungszentrum Jülich technology and manufacturing process concepts are developed for the production of stationary and mobile fuel cell stacks based on the material development of the participating research institutes. Of crucial importance is the use of self developed glass solders as joining and insulation medium. The use of soldering materials has been limited to the furnace technology with small heating and cooling rates. The potential of the laser as a flexible tool for the manufacture and repair of fuel cell stacks invention are to be evaluated as part of a research study. The high power density of laser radiation-induced heating rates influence the properties of the glass solders and their interaction significantly with metallic materials. First results on applications of different laser sources as joining tool in production of fuel cell invention are shown and explained their application-related properties.
