Anode‐Supported Solid Oxide Fuel Cell Achieves 70 000 Hours of Continuous Operation

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 70 000 h (eight years)—the longest operation time ever reached for this technology. This result offers the best prospect for the realization of stable and robust SOFC technology.
