                      introduction. Therefore, extended lifetime tests are
                      essential for learning about the long-term behavior and
                      various degradation mechanisms and to foster ideas about
                      accelerated stack testing. The Forschungszentrum Jülich has
                      been gradually extending the testing time, resulting in
                      successful short-stack operating times of between 20,000 and
                      40,000 h. This work highlights the results of these
                      long-term tests and compares the observations for different
                      material combinations, operating temperatures of 700 and 800
                      °C, including different fuel utilizations and gas
                      compositions. An increase of temperature from 700 to 800 °C
                      leads to an acceleration of the degradation rate by a factor
                      of 1.5–2. Meanwhile, an increase in fuel utilization from
                      40 to $80\%$ did not result in increased degradation. The
                      same was found for higher current densities of up to 1
