摘要

中温固体氧化物燃料电池(IT-SOFC)比传统的SOFC具有更广泛的材料使用、更低的制造成本和更长的电池组件寿命,从而提供了经济和技术优势。在这项工作中,我们使用低成本材料制造了电解质支持的IT-SOFC,如通过干法压制制造的钙稳定的氧化锆(CSZ)电解质、NiO-CSZ阳极和通过刷涂技术生产的Ca3Co1.9Zn0.1O6(CCZO)阴极。根据XRD结果,单斜相以立方相为主,电解质的相对密度较低,但CSZ电解质的硬度接近商业8YSZ电解质的强度。单电池的性能是在氢气环境空气中进行的。在600、700和800°C的工作温度下,分别获得0.43、0.46和0.45 V的开路电压(OCV)和0.14、0.50和1.00 mW/cm2的最大功率密度。由于电极和电解质中的厚电解质和Cr中毒,电池在700和800°C下的欧姆电阻分别达到81.5和33.00Ω

Performance Evaluation of An Electrolyte-Supported Intermediate-Temperature Solid Oxide Fuel Cell (IT-SOFC) with Low-Cost Materials
Intermediate temperature solid oxide fuel cell (IT-SOFC) provides economic and technical advantages over the conventional SOFC because of the wider material use, lower fabrication cost and longer lifetime of the cell components. In this work, we fabricated electrolyte-supported IT-SOFC using low-cost materials such as calcia-stabilized zirconia (CSZ) electrolyte fabricated by dry-pressing, NiO-CSZ anode and Ca3Co1.9Zn0.1O6 (CCZO) cathode produced through brush coating technique. According to the XRD result, the monoclinic phase dominated over the cubic phase, and the relative density of the electrolyte was low but the hardness of the CSZ electrolyte was close to the hardness of commercial 8YSZ electrolyte. The performance of the single cell was performed with hydrogen ambient air. An open-circuit voltage (OCV) of 0.43, 0.46, and 0.45 V and a maximum power density of 0.14, 0.50, and 1.00 mW/cm2 were achieved at the operating temperature of 600, 700, and 800 °C, respectively. The ohmic resistance of the cell at 700 and 800 °C achieved 81.5 and 33.00 Ω, respectively due to the contribution of thick electrolyte and Cr poisoning in electrodes and electrolyte
