A 4 × 4 cm2 Nanoengineered Solid Oxide Electrolysis Cell for Efficient and Durable Hydrogen Production
Abstract
Despite various advantages of high-temperature solid oxide electrolysiscells (SOECs) over their low-temperature competitors, the insufficientlong-term durability has prevented the commercialization of SOECs. Here,we address this challenge by employing two nanoengineered electrodes.The O<sub>2</sub> electrode consists of a La<sub>0.6</sub>Sr<sub>0.4</sub>CoO<sub>3−δ</sub> (LSC) and Gd,Pr-co-doped CeO<sub>2</sub> (CGPO) nanocomposite coating deposited on a Gd-doped CeO<sub>2</sub> (CGO) scaffold, and the H<sub>2</sub>electrode comprises a Ni/yttria stabilized zirconia (YSZ) electrodemodified with a nanogranular CGO coating. The resulting cell with anactive area of 4 × 4 cm<sup>2</sup> exhibits a current density exceeding 1.2 A cm<sup>–2</sup> at 1.3 V and 750 °C for steam electrolysis while also offering excellent long-term durability at 1 A cm<sup>–2</sup>with a high steam-to-hydrogen conversion of ∼56%. We further unravelthe degradation mechanism of the most commonly used Ni/YSZ electrodeunder these conditions and describe the mitigation of the discussedmechanism on our nanoengineered electrode. Our findings demonstrate thepotential of designing robust SOECs by nanoengineering electrodesthrough infiltration and have significant implications for the practicalintegration of SOEC technology in the future sustainable energy system.
