Purpose and goal
The goal of the project was to develop a steel based solid oxide fuel cell and to give Johanna Stiernstedt possibilities to qualify to become associate professor, as well as senior scientist at Swerea IVF. Johanna is now senior scientist and has during the project earned most of the requirements to become associate professor. The coefficient of thermal expansion and the shrinkage have been adapted between the anode and electrolyte materials. The sintering temperature has been decreased, but not enough to make steel and ceramic compatible.
Results and expected effects
The project result could be a base for a more effective manufacturing method of fuel cells, but the technique has not been possible to expand to the more robust steel based SOFC. Through the academic research Johanna Stiernstedt has had the possibility to attend several conferences, in addition to courses, teaching and supervising master students. The industrial contacts and cooperation was a contributing factor for her to become senior scientist.
Approach and implementation
The materials for SOFC were chosen from their electrophysical properties; at the same time material and manufacturing methods were developed. The project combined academic and applied research, and the cooperation with Chalmers and Höganäs has been successful. The materials have been characterized and modified and become better and more compatible. However, the sintering temperature was not possible to decrease enough for the steel carrier.
