Special Issue Information

Dear Colleagues,

Mixed ionic–electronic conducting (MIEC) membranes have attracted considerable attention from both academia and industry due to their broad range of potential for energy- and environmental-related applications. MIEC membranes have been considered as a prominent next-generation technology for energy conversion and storage and demonstrate an important role in the ongoing energy transition. There is no doubt that MIEC membranes will play a vital role in various energy conversion and storage applications.

This Special Issue of the journal Membranes titled “Sustainable Mixed Ionic–Electronic Conducting Membranes for Environmental and Energy Applications” seeks contributions to assess state-of-the-art technologies, the latest developments and future challenges and opportunities of MIEC membranes. Topics include, but are not limited to, membranes for H2 and O2 production, membranes for CO2 conversion, membranes for CO2 separation, membrane reactors for the production of chemicals, membranes for O2 and H2 separation, cathode development for solid oxide fuel cells, protonic ceramic fuel cells, solar-driven evaporation processes, electrolyzer cells for power-to-X technologies, modeling for oxygen and hydrogen transport, new material development, new fabrication techniques, industrial exploitation and new processes using MIEC membranes. Both original articles, perspectives and reviews are welcome.

We are looking forward to receiving your work for this Special Issue.

High-entropy perovskite oxides have already been studied in various fields owing to their high-entropy-induced properties. Partial substitution of an element by a lower valence element usually improves the oxygen permeability of perovskite oxides, but high substitution amounts may lead to structural instability. In this work, pure high-entropy perovskites Pr1xSrx(Cr,Mn,Fe,Co,Ni)O3δ with high amounts Sr up to x=0.5 were synthesized via a sol–gel method. Several characterization methods prove that the solubility of Sr increases with higher temperatures of the heating treatment. The ceramic with x=0.5 shows a transition from semi-conductive to metallic behavior when the temperature reaches 873 K. Its oxygen flux is comparable to the low-entropy counterpart La0.6Sr0.4Co0.5Fe0.5O3δ. A stable run of ca. 46.2 h was documented for oxygen permeation under an air/CO2 gradient. Full article

The performance and durability of proton exchange fuel cells (PEMFCs) are greatly affected by the bipolar plate (BP). In this paper, the thermal and electrical conductivities and mechanical property of graphite filled with resin composite BPs were collectively enhanced through the effectively coupled manipulations of molding pressure and impregnation pressure. The microstructures show that the resin tends to distribute at the top region of the rib under high impregnation pressure. The thermal and electrical conductivities of the pure expanded graphite BP is well reserved in the composite BPs under high molding pressure, which can facilitate the heat transfer and electron conduction in the PEMFCs. The relative density and compressive strength of composite BPs were greatly enhanced by the impregnation of resin compared to the expanded graphite under high molding pressure without the impregnation of resin (HU-BP). The maximum thermal conductivity, compressive strength, and minimum interfacial contact resistance (ICR) are collectively achieved in the HL-BP. The enhanced thermal-electrical and mechanical properties could be mainly attributed to the well-reserved continuous networks of graphite in the composite BPs. The findings in this paper are expected to synergetically improve the thermal, electrical, and mechanical properties of composite BPs through coupled manipulations of the molding and impregnation pressures, which in turn enhances the power density and durability of PEMFCs.
