SOC Development at Forschungszentrum Jülich

In order to become a substantial part of the energy supply infrastructure in the course of the German "Energiewende" (energy system transition), SOFC plants in the power range of 100 kW or larger must be realized. Scale-up of units will become even more important in the field of electrolysis to balance electricity conversion and consumption. Therefore, currently one of the main goals of SOC development at the Forschungszentrum Jülich is the development of single stacks in the 15 kW power range as a basis for realization of larger units. Initial operational results with the adapted stack design are reported. Results of long-term operation in fuel cell and in electrolysis mode are presented as well as activities in the field of systems development and operation. This also includes the development of a 5 kW rSOC (reversible Solid Oxide Cell) system.
