Special Issue Information

Dear Colleagues,

The Special Issue, entitled "Membrane-related Materials for Fuel Cell and/or Battery Applications", is dedicated to exploring cutting-edge advancements in those materials crucial for the development and enhancement of fuel cells and batteries. Membranes play a pivotal role in the performance and efficiency of these energy storage technologies, influencing key factors such as conductivity, selectivity, and overall durability. This interdisciplinary platform invites researchers, scientists, and engineers to contribute their latest findings, innovative methodologies, and insightful perspectives on membrane-related materials.

The scope of the Special Issue encompasses a broad range of materials, including, but not limited to, polymers, ceramics, and hybrid materials, designed to address challenges and push the boundaries of fuel cell and battery technologies. Contributions may delve into novel synthesis techniques, characterization methods, theoretical studies and modeling, and performance evaluations of membrane materials, fostering a comprehensive understanding of their fundamental properties and potential applications.

Researchers are encouraged to explore diverse aspects, such as membrane design for specific applications, improvements in proton or ion conductivity, and strategies to enhance the mechanical properties and stability of membranes under various operating conditions. Furthermore, investigations into the compatibility of membrane materials with different electrolytes and electrode materials will contribute to the overall knowledge base in the field.

The Special Issue aims to serve as a valuable resource for the scientific community, providing a platform for the exchange of ideas and insights that will drive advancements in membrane-related materials, ultimately contributing to the progress of fuel cell and battery technologies. As the energy landscape continues to evolve, this collection of research will play a pivotal role in shaping the future of sustainable and efficient energy storage systems.

Proton ceramic fuel cells offer numerous advantages compared with conventional fuel cells. However, the practical implementation of these cells is hindered by the poor sintering activity of the electrolyte. Despite extensive research efforts to improve the sintering activity of BCZY, the systematic exploration of the utilization of NiO as a sintering additive remains insufficient. In this study, we developed a novel BaCe0.55Zr0.35Y0.1O3-δ (BCZY) electrolyte and systematically investigated the impact of adding different amounts of NiO on the sintering activity and electrochemical performance of BCZY. XRD results demonstrate that pure-phase BCZY can be obtained by sintering the material synthesized via solid-state reaction at 1400 °C for 10 h. SEM analysis revealed that the addition of NiO has positive effects on the densification and grain growth of BCZY, while significantly reducing the sintering temperature required for densification. Nearly fully densified BCZY ceramics can be obtained by adding 0.5 wt.% NiO and annealing at 1350 °C for 5 h. The addition of NiO exhibits positive effects on the densification and grain growth of BCZY, significantly reducing the sintering temperature required for densification. An anode-supported full cell using BCZY with 0.5 wt.% NiO as the electrolyte reveals a maximum power density of 690 mW cm−2 and an ohmic resistance of 0.189 Ω cm2 at 650 °C. Within 100 h of long-term testing, the recorded current density remained relatively stable, demonstrating excellent electrochemical performance. Full article

The phase inversion tape casting has been widely used to fabricate open straight porous supports for solid oxide fuel cells (SOFCs), which can offer better gas transmission and minimize the concentration polarization. However, the overall weak strength of the macro-porous structure still limits the applications of these SOFCs. In this work, a novel SOFC supported by an ordered porous cathode membrane with a four-layer configuration containing a finger-like porous 3 mol% yttria- stabilized zirconia (3YSZ)-La0.8Sr0.2Co0.6Fe0.4O3−δ (LSCF) catalyst, porous 8 mol% yttria-stabilized zirconia (8YSZ)-LSCF catalyst, and dense 8YSZ porous 8YSZ-NiO catalyst is successfully prepared by the phase inversion tape casting, dip-coating, co-sintering, and impregnation process. The flexural strength of the open straight porous 3YSZ membrane is as high as 131.95 MPa, which meets the requirement for SOFCs. The cathode-supported single cell shows a peak power density of 540 mW cm−2 at 850 °C using H2 as the fuel. The degradation mechanism of the SOFC is investigated by the combination of microstructure characterization and distribution of relaxation times (DRT) analysis. Full article
