固体氧化物电解池材料和结构优化的研究进展OA

Solid oxide electrolysis cells(SOEC),as a new generation of high-temperature electrochemical energy conversion devices,offer substantial advantages in distributed energy storage and renewable energy utilization through theefficient conversion of electrical energy into chemical energy.Furthermore,SOEC can be effectively integrated with photovoltaic or solar thermal systems,enabling the flexible conversion of intermittent electrical energy into storable hydrogen.Moreover,SOEC can coelectrolyze CO2 and H2O,enabling the efficient conversion of greenhouse gases into clean fuels,such as methanol and methane,via chemical chain conversion processes.This establishes a cascading resource utilization system known as the"electricity-hydrogen-chemicals"framework.This review provides a systematic overview of the thermodynamic foundations and structural characteristics of SOEC,with emphasis on recent advances in fuel electrodes,oxygen electrodes,and electrolyte materials.It also examines the current challenges confronting SOEC technology and summarizes improvement strategies in electrode material development,cell architecture,flow-field optimization,and thermal management.Finally,it outlines potential development pathways for SOEC in coelectrolysis and the advancement of low-carbon energy systems.
