| الوصف: | Hydrogen energy, central to modern energy storage, is promising for use in solid oxide electrolysis cells (SOECs) due to its efficiency and production rate. However, the degradation of SOECs, possibly due to altered oxygen distribution, remains a significant challenge. This study introduces light as a method to stabilize the oxygen distribution and enhance oxygen vacancies, thus countering cell degradation. Using an LSM/GDC/YSZ/Ni-YSZ SOEC, we illuminated the LSM anode and identified a unique “light healing effect” (LHE). This effect, distinct from the photothermal influence, showcased a photoinduced hydrogen yield improvement of 270.1 mmol/m 2 /h, an 11.7% increase over that in the dark, at 800 °C and 0.8 V. In the stability test, the cell exhibited no degradation and remained stable for 50 h with the LHE, compared to a 10.95% decrease in the dark. We consistently observed the LHE across diverse tests, including tests with traditional anodes (LSM, LSC, and LSCF) and orthogonal experiments ranging from 600 to 800 °C and from 0.8 to 2 V. Our findings suggest that the LHE mechanism may be tied to the creation and buildup of photoinduced oxygen vacancies, which indicates an innovative way to avoid deactivation and even improve the performance of SOEC systems. |
