Energy research is one of the priority tasks for the future within the framework of the Federal Government's High-Tech Strategy. Combined heat and power (CHP) in the stationary sector is a key technology for the resource-efficient use of fossil fuels. The highest efficiency of around 90 % is achieved with SOFC-based systems. A strongly growing market is forecast for these, which is driving research into products with a longer service life at lower costs. Within the framework of KerSOLife100, a consortium of industrial and scientific partners is researching an innovative, promising all-ceramic SOFC cell concept for cost-efficient μCHP, which has a high potential to meet future market requirements in terms of service life and costs. In this concept, low-cost materials not previously used for SOFCs are to be used in combination with novel process technologies. Therefore, there is a considerable risk that as yet unknown ageing phenomena and damage will occur. These must be controlled in order to successfully place such systems on the market. Research into the degradation mechanisms and understanding-based remedial measures at the levels of material, construction and production technology as well as operating strategy are therefore indispensable from an economic point of view - and of great scientific interest. This also includes the development of a procedure for knowledge-based, accelerated testing in order to be able to reliably evaluate the optimisation of materials and specific process technologies and guarantee the required service life.
