Which risk increases when increasing burner temperature abruptly in a solid oxide electrolyzer cell (SOEC)?

💡 Explanation

Rapid temperature excursions lead to differential thermal expansion, thus the failure risk is rapid electrode-electrolyte delamination. This occurs because of thermal shock, therefore the electrodes separate rather than maintain electrochemical equilibrium, because the protective ramp times minimise stress.
