摘要

解决低温下较差的电化学性能和不确定的法拉第效率（FE）所带来的挑战，是开发高性能、高效质子传导固体氧化物电解电池（P - soec）的关键任务。本文首次设计并合成了一种新型氧电极材料BaCo0.8Zr0.1Zn0.1O3‐δ (BCZZ)。在600°C下，具有BCZZ氧电极的P‐soec在1.3 V下的电解电流密度为1.98 A cm−2,FE≈90%。利用1英寸P‐soec作为可靠的平台，进一步系统地研究了P‐soec的外部操作条件（即蒸汽浓度、电压、电流密度和温度）和内在特性（即电解质材料和电解质厚度）对FE的影响。

An Active Oxygen Electrode for Proton‐Conducting Solid Oxide Electrolysis Cells with High Faradaic Efficiency

Addressing the challenges posed by inferior electrochemical performance at low temperatures and the uncertain Faradaic efficiency (FE) represents a pivotal undertaking in the development of high performance and efficient proton‐conducting solid oxide electrolysis cells (P‐SOECs). In this work, a novel oxygen electrode material BaCo0.8Zr0.1Zn0.1O3‐δ (BCZZ) is first designed and synthesized. At 600 °C, P‐SOECs with BCZZ oxygen electrode achieve an electrolysis current density of 1.98 A cm−2 with an ≈90% FE at 1.3 V. Utilizing 1‐inch P‐SOECs as a reliable platform, the effect of extrinsic operating conditions (i.e., steam concentration, voltage, current density, and temperature) and intrinsic properties of P‐SOECs (i.e., electrolyte material and electrolyte thickness) on FE are further systemically investigated, both experimentally and theoretically.
