In 3D-POWER we used robocast 3D printing technique, a type of Additive Manufacturing (AM), for fabrication of electrodes for solid oxide fuel cells (SOFC) and batteries. This was an effort to find the alternative to present day SOFC fabrication techniques which involve expensive, time-consuming multi-step processes as well as limit the design to flat plates or tubes. AM has been reasonably well established for the production of conventional ceramic parts with complex geometries, but little attention has been given to its use in fabrication of energy devices. Thus,this project dealt with an exciting and novel avenue to realize 3D printed SOFC electrodes and fabricate innovative geometries which potentially lead to higher levels of performance. In these activities we were successful to fabricate symmetric SOFC cell using LaSrMnO as an 3D-electrode on YSZ substrate. Moreover LSGM and CGO materials were also successfully implemented as an electrolyte. The achieved results are comparable with the available data in literature using conventional tape casting technique. Full SOFC cell was realized with 3D-printed electrodes with YSZ or LSGM electrolytes and its electrochemical performance was tested using Impedance spectroscopy. This work is in accordance with the Work Packages 1 and 2. For WP 3 i.e. Dissemination of knowledge/Results variety of activities were undertaken and have been mentioned in details in attached Periodic Technical Report Part B. To highlight a few- An Invited talk has been delivered at ‘Researcher Link Workshop between India and UK on Generation, Storage and Utilization of Renewable Hydrogen: Towards Sustainable Energy’ at Agra, India, allowing main researcher Dr. Kawale to build new collaborations within India and EU. Variety of conferences, day symposiums and meetings have been attended. For example a poster entitled ‘Interface engineering in LiNi0.5Mn1.5O4 (cathode) / LLZO (electrolyte) based solid-state batteries’ was presented at Interfaces in Energy Materials Conference, Trinity College, Cambridge, UK, in April 2018. To disseminate results and progress under 3D-POWER international event like 233rd Electrochemical Society (ECS) Meeting at Seattle in June 2018 was been attended allowing establishing new collaborations internationally. Academic Lab visits and Industrial visit were also undertaken- which allowed injections of new perspectives and ideas in to the research work carried under 3D-POWER project.
