Improved SOFC stacks: Power density, durability and modularity

SOFC technology potentially offers a clean and efficient way of producing electricity and heat from a wide selection of fuels. However, before SOFC can be introduced for larger stationary applications, further cost reduction and a strategy for scaling the present 1-3 kW SOFC stacks to 50-250 kW systems is needed. Stack components (WP1): Improved stack components will contribute to improve stack lifetime, facilitate the application of cells with more active cathode materials, and enable the design and build of high-power stacks for larger SOFC systems. Stacks and durability (WP2): SOFC stack technology has matured to the point where stack lifetime is now in focus. This work package aims at improving long term (greater than 3000 h) durability under realistic operating conditions, and at using cells with more active cathode materials. The reduced operating temperatures of these cells provide an alternative route to improved durability. Large SOFC systems: modularity and scalability (WP3): Based on the present 1 - 3 kW stack technology, this work package intends to develop designs for larger stacks relevant for SOFC systems in the 50 kW - 250 kW power range
