However, this technology is still subject to limitations, such as insufficient cycling stability and long start-up times. With the use of a thin proton-conducting electrolyte and a metallic support it is expected to overcome these limitations. To manufacture such a cell, the membrane electrode assembly is wet-chemically deposited onto the metallic support and then thermally crystallized. Conventional methods (Rapid Thermal Annealing or oven) lead to unwanted interactions with the substrate material. The use of a laser beam for thermal crystallization of the thin films allows very short processing times and therefore offers the potential to completely crystallize the thin films without the formation of minor phases. In this work electrolyte material is crystallized using a laser beam, and the influence of different process parameters is investigated using X-ray diffraction and transmission electron microscopy.ensolid oxide fuel cellslaser processingcrystallizationthin filmsconference paper
