Front cover image: Solid oxide electrolytic cell (SOEC) is an efficient energy conversion device, which can transfer power to gas and realize storage. In article number: 10.1002/cey2.262, Wu et al. proposed the pulsed current strategy replicate intermittent renewable energy, investigated stability rate of flat-tube SOEC under cyclic CO2 electrolysis operation, indicating significant advantages in electrochemical conversion, carbon emission mitigation, seasonal
