Special Issue Information

Dear Colleagues,

I am pleased to invite you to submit the results of your recent studies in the field of “Preparation and Optimization of Solid Oxide Fuel/Electrolysis Cells (SOFCs/SOECs)” to a Special Issue of Energies.

Today, the ever-increasing energy demand and the tightening regulations for emissions control have aroused a significant amount of interest in developing more efficient power generation systems. Hydrogen is regarded as the ideal energy source for the future because of its advantages of zero carbon emission, zero pollution, high efficiency, and widely available sources. In recent years, the methods for using and producing hydrogen have attracted much attention. The solid oxide fuel cell (SOFC) is considered one of the most promising alternative techniques for using hydrogen to produce electricity. Further, as the reverse process of the SOFC, the solid oxide electrolysis cell (SOEC) has been considered an effective technology for producing hydrogen at a low cost, with high efficiency and environmental friendliness. The SOEC can use waste heat from nuclear power plants and other industrial processes for high-temperature electrolysis of water, which can reduce the amount of electricity needed to produce hydrogen. In addition, no pollutants are discharged at any time during the reaction process, indicating that both SOFC and SOEC are environmentally friendly.

Therefore, the focus of this Special Issue of Energies will be on the development of alternative SOFC/SOEC materials and novel techniques for the fabrication of SOFC/SOEC. The key topics covered by this Special Issue include but are not limited to the following:

  • New SOFC/SOEC structures (e.g., tubular, flat tubular, planar, segmented-in-series, metal-supported);
  • Low-temperature SOFC/SOEC techniques;
  • Synthesis and characteristics of the SOFC/SOEC anode, electrolyte, interconnects, and cathode materials;
  • Microstructural improvement of the SOFC/SOEC supporting layers;
  • Novel fabrication methods and stack design techniques;
  • Numerical studies and diagnostic methods;
  • Other methods to use or produce hydrogen.

Solid oxide co-electrolysis cells can utilize renewable energy sources for the conversion of steam and carbon dioxide into valuable chemicals and feedstocks. An important challenge in the analysis of these devices is understanding the reaction pathway(s) that govern carbon monoxide generation. Studies in which co-electrolysis polarization lies between those of pure steam and pure carbon dioxide electrolysis suggest that carbon dioxide electro-reduction (CO2ER) and the reverse water gas shift (RWGS) reaction are both contributors to CO generation. However, experiments in which co-electrolysis polarization overlaps that of pure steam electrolysis propose that the RWGS reaction dominates CO production and CO2ER is negligible. Supported by dimensional analysis, thermodynamics, and reaction kinetics, this work elucidates the reasons for which the latter conclusion is infeasible, and provides evidence for why the observed overlap between co-electrolysis and pure steam electrolysis is a result of the slow kinetics of CO2ER in comparison to that of steam, with the RWGS reaction being inconsequential. For sufficiently thin cathode current collectors, we reveal that CO2ER is dominant over the RWGS reaction, while the rate of steam electro-reduction is much higher than that of carbon dioxide, which causes the co-electrolysis and pure steam electrolysis polarization curves to overlap. This is contrary to what has been proposed in previous experimental analyses. Ultimately, this work provides insight into how to design solid oxide co-electrolysis cells such that they can exploit a desired reaction pathway in order to improve their efficiency and product selectivity.

Thermal management systems for lithium-ion batteries based on the cooling and heating of phase change materials have become a popular research topic. However, the low thermal conductivity, flame resistance, high and low temperature adaptability of phase change materials, as well as the thermal runaway mechanisms and lightweight design of phase change material-based systems remain to be explored. The aim of this paper is to conduct a publication-wide macro bibliometric review on thermal management systems for lithium-ion batteries based on phase change material to date. Total of 583 associated publications were retrieved from the Web of Science Core Collection database for the period 2006–2022. A bibliometric study was conducted through the visualization software VOSviewer. The findings were derived from annual publication trends, geographical and institutional distribution, authors and their collaborative networks, keyword network analysis and analysis of highly cited publications as well as reference co-citation analysis. The findings provide a comprehensive overview of the evolution of research hotspots in the field and can help researchers who would like to work in the field to quickly grasp the research frontiers and the overall picture. Furthermore, some suggestions for future work are summarized. Full article
