Abstract

Solid oxide fuel cells (SOFCs) supported on ceramic anodes exhibit superior redox stability and mechanical strength compared to those supported on Ni-yttria stabilized zirconia (YSZ) cermet anodes. In the present study, an anode-supported all-ceramic SOFC containing a 400 μm thick Sr_1.9Fe_1.4Ni_0.1Mo_0.5O_6-δ (SFNM)@YSZ anode, a 10 μm thick dense YSZ electrolyte and a 30 μm thick LaCoO₃ (LCO)@YSZ cathode was prepared using the phase inversion tape casting, dip-coating, co-sintering and impregnating processes. The single cell achieved a remarkably high peak power density of 1411 mW•cm⁻² at a high temperature of 800 °C and an appreciable power density of 241 mW•cm⁻² at an intermediate temperature of 650 °C. This all-ceramic cell maintained its integrity after 10 redox cycles. Future research is required to optimize the composition and microstructure of the impregnated perovskite nanoparticle electrocatalysts to enhance the power density at intermediate temperatures.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
