Development of improved SOFC cell and stack technology and improved production methods

This project demonstrated that cells may be produced with an area larger than 500 cm2. An improved cathode based on LSCF-CGO composite will also be demonstrated. It has now been tested for more than 3,000 hours with humidified air and natural gas. The project demonstrated design, assembling and operation of a stack with a cell area of 18x30 cm. It was also demonstrated how a significantly lower gas leakage can be achieved by optimising the mechanical design in the sealing area. Additionally, the project proved how incorporating Cr-getters in the stack design decreases degradation significant. (Energy 10)
