Proton-conducting solid oxide electrolysis cells (H-SOECs) have gained significant attention due to their advantages over ion-conducting SOECs (O-SOECs). However, progress in H-SOECs lags behind O-SOECs, primarily due to the low stability of electrolytes in environments with H2O and CO2. This review critically evaluates recent developments in H-SOECs and discusses future research directions.
Proton-conducting solid oxide electrolysis cells (H-SOECs) have attracted significant attention in recent years. This is due to their advantageous nature compared with the popular ion-conducting SOECs (O-SOECs). Progress in H-SOECs is, however, lagging compared with O-SOECs. This is primarily due to the low stability of these electrolytes in environments that contain H2O and CO2. Here, we present a critical evaluation, recent developments, overview of advancements, and future perspective for H-SOECs (emphasizing the last decade of work on H-SOECs). We focus on the design and advanced interface architecture of electrodes and the composition-structure-property relationship of the most popular Ba(Ce, Zr)1_x_yYxYbyO3_8 and Sr(Ce, Zr)1_x_yYxYbyO3_8 ma-terials. We also present the latest innovative electrolyte materials applicable to H-SOECs and introduce the latest reported modifica-tion techniques for enhancing overall H-SOEC performance. Finally, we assess the prospects and potential direction of research for the near future.
