Special Issue Information

Dear Colleagues,

Solid oxide fuel cells (SOFCs) can be a driving force that will change the course of action for automobiles and household devices in the modern era due to its optimal power generation features with maximum electrical efficiency. A typical SOFC consists of a cathode, anode, and an electrolyte constituting a single cell. The electrocatalytic activity of electrode materials has significant influence on the single cell performance. This Special Issue is intended as a collection of contributions regarding electrode materials with high electrocatalytic activity of solid oxide fuel cells, in order to build and consolidate the knowledge in this subject area. It is our pleasure to invite you to submit a full paper, detailed review, or significant preliminary communication related to efficient electrode materials for solid oxide fuel cells.

Ba0.5Sr0.5FeO3−δ (BSF) nanofibers are prepared via electrospinning and sintering at a temperature of 800 °C for 2 h to produce a pure cubic perovskite phase, with the aim of finding a high-performance cathode material suitable for proton-conducting solid oxide fuel cells (PCFCs) operating at medium temperatures. The results of SEM analysis showed that the BSF nanofibers are alternately stacked, presenting fluffy and uniform high porosity, which is favorable to the cathode polarization reaction of PCFCs. To balance the excessive coefficient of thermal expansion of the BSF cathode, it is combined with a negative thermal expansion (NTE) material NdMnO3−δ (NM). At 700 °C, the peak power density (PPD) of the BSF–NM cathode cell is 1170 mW cm−2, and the open-circuit voltage (OCV) of the single cell is 1.04 V. The corresponding polarization impedance (Rp) of the BSF–NM is 0.037 Ω cm2. This result is significantly better than the previously reported powder cathode BSF, indicating that the performance of PCFC can be further optimized by transforming the BSF cathode into a nanofiber state and compounding it with the NTE material NM.
