Abstract The ceramic thick-film technology allows the build-up of miniaturised and robust integrated multilayer-circuits and sensors by means of sequential screen-printing and firing of different functional materials. However, the manufacturing of integrated electronics does not succeed if the components are temperature sensitive or too large for the process in a sintering furnace. At present, large components like wind power rotors, axles or roller bearings are monitored by vulnerable hybrid sensor systems. In order to implement the advantages of integrated devices, like the direct surface contact and the high thermomechanical stability, functional ceramic-based materials are adapted or newly developed to accommodate the needs of laser sintering techniques of printed sensor layers on structural components. In a first approach, screen printed thick films on steel components are investigated. The defect-free densification of functional layers crucially depends on the particular material composition in combination with adapted laser treatment. A first generation of functional layers is presented, comprising isolating, conductive, and resistive electrical materials. The films are tested in demonstrator setups and show functional properties comparable to those of the furnace sintering technology. Future aspects of material optimization and the adaption to specific application requirements will be discussed.

This paper presents an overview of recent advances in the synthesis and preparation of solid oxide fuel cells (SOFCs) functional ceramic materials, focusing on low-/intermediary-temperature SOFCs. Novel synthesis processes for oxygen ion-conducting and mixed electronic and ionic conductors, fundamental to reduce the operating temperature of SOFCs were studied. Ni-Ce0.9Gd0.1O1.95 (Ni-CGO) anodes were successfully synthesized by the so called “one step synthesis”. La0.5Sr0.5Co0.8Fe0.2O3 (LSCF), Ce0.8Sm0.2O1.9 (SDC) and their mixture were produced as a cobaltite-based composite cathode by mixing powders synthesized by microwave-assisted combustion and the modified polymeric precursor method, respectively. Preliminary electrochemical activity tests with the synthesized electrodes were performed in electrolyte-supported SOFCs using commercially available 200 µm thick yttria stabilized zirconia (8YSZ) as electrolyte. The maximum power density of 52 mW/cm2 was reached at 850 °C. This result can be further improved replacing thick YSZ electrolytes by doped-ceria thin films, aiming at operation temperatures of 500–800 °C and power densities as high as 800 mW/cm2. The assembling of anode-supported cells with the configuration Ni-CGO/CGO (10 µm thickness)/LSCF-SDC are for applications in 2 kW stacks are currently under way.
