Global climate challenges necessitate the development of technologies that reduce civilization's dependence on non-renewable resources. Very promising in this respect are solid oxide fuel cells (SOFCs). However, their high operating temperatures have imposed a variety of practical limitations, and therefore a major focus in recent years has been on new materials and optimized microstructures. Here, we report the results of a long-term test using a short stack with anode-supported cells based on standard materials, and we attained a continuous operation time of 70000h (eightyears)the longest operation time ever reached for this technology. This result offers the best prospect for the realization of stable and robust SOFC technology.
