Constraints in sustainable electrode materials development for solid oxide fuel cell: A brief review

Materials Science for Energy Technologies, Journal Year: 2024, Volume and Issue: 8, P. 32 - 43

Published: July 14, 2024

Solid oxide fuel cells (SOFCs) are efficient electrochemical energy device that converts the chemical of fuels directly into electricity. It has a high power and density sustainable source energy. The electrode (cathode anode) materials essential for operation SOFCs. Several have been studied in last two decades, mainly perovskite materials. investigated resulted improved performance SOFCs, increased commercial viability, reduced operational costs. However, sustainability most material compositions (heteroatoms) used as electrodes SOFCs never investigated. present study examines recent progress, challenges, constraints associated with development from perspective. Heteroatoms majorly employed doping materials' long-term availability on earth's surface was established. also provides an overview current state symmetrical solid cells. This is intended to address complexities different anode cathode.

Valence Variability Induced in SrMoO₃ Perovskite by Mn Doping: Evaluation of a New Family of Anodes for Solid-Oxide Fuel Cells

Materials, Journal Year: 2025, Volume and Issue: 18(3), P. 542 - 542

Published: Jan. 24, 2025

We report on a series of SrMo1−xMnxO3−δ perovskite oxides designed as potential anode materials for solid oxide fuel cells (SOFCs). These were synthesized using citrate method, yielding scheelite-type precursors with nominal SrMo1−xMnxO4 compositions, which further reduced to obtain the active oxides. Their structural evolution was examined through X-ray diffraction (XRD) and neutron powder (NPD). techniques provided insights into crystallographic changes upon Mn doping, revealing key factors influencing ionic conductivity. Whereas oxidized scheelite are tetragonal, space group I41/a, specimens cubic, Pm-3m, show conspicuous absence oxygen vacancies, even at highest temperature 800 °C. The transport properties analyzed electrical conductivity measurements, exhibiting metallic-like behavior. Thermogravimetric analysis (TGA) dilatometry give thermal stability expansion behavior, essential SOFC operation. Test single SOFCs built in an electrolyte-supported configuration, LSGM pellets 300 μm thickness, assessing performance title anodes. This work emphasizes critical relationship between crystal structure its electrochemical providing deeper understanding how doping strategies can optimize cell performance.

Published: March 31, 2025

This research investigates the development and analysis of Yttria Stabilized Zirconia (YSZ) thin film electrolytes for low-temperature Solid Oxide Fuel Cells (LT-SOFCs) using sol-gel dip coating method. YSZ is valued its high ionic conductivity thermal stability, which are vital SOFC operation at reduced temperatures. The technique offers a versatile cost-effective approach to control thickness microstructure. In this study, films synthesized by varying precursor concentrations, period annealing temperatures optimize properties. Structural X-ray diffraction (XRD) confirms formation crystalline phase while Scanning electron microscopy (SEM) reveals uniform dense Results indicate that with higher 4 g longer periods, 15 min show increased surface roughness porosity. Atomic force (AFM) measurements reveal values ranging from 57.5 nm 172.0 solutions, 2 solutions exhibit between 80.3 238.8 nm. SEM images denser but more porous could affect mechanical electrical Contact angle nucleation follows Frank-van der Merwe growth mechanism, angles 20⁰ 80⁰ depending on conditions.
