Special Issue Information

Dear Colleagues,

I am pleased to invite you to submit your recent studies in the field of “Cathode Materials and Structural regulation for proton-conducting Solid Oxide Fuel Cells” to a Special Issue of Molecules.

Nowadays, the trend towards sustainable living has prompted the development of materials and technologies which can convert energy efficiently. Proton-conducting solid oxide fuel cells (H-SOFCs) are promising devices that can operate and convert chemical molecular energy to electricity at intermediate temperatures due to their high energy conversion efficiency.

Develo** appropriate cathode materials that can demonstrate satisfactory performance has become a primary challenge for the practical application of H-SOFCs. Many cobalt-based cathodes have been extensively studied for H-SOFCs in recent years. However, their electrochemical performance is still lower than that of oxygen-ion-conducting SOFCs. Significant advances in cathode materials and microstructure modification for H-SOFCs have been achieved in the last decades and are still an important target in the current research.

This Special Issue aims to provide a forum for researchers to present current and recent developments in novel cathode materials and structure. Original research papers, review articles and short communication letters are all welcome.

Fuel cells are at the forefront of modern energy research, with graphene-based materials emerging as key enhancers of performance. This overview explores recent advancements in graphene-based cathode materials for fuel cell applications. Graphene’s large surface area and excellent electrical conductivity and mechanical strength make it ideal for use in different solid oxide fuel cells (SOFCs) as well as proton exchange membrane fuel cells (PEMFCs). This review covers various forms of graphene, including graphene oxide (GO), reduced graphene oxide (rGO), and doped graphene, highlighting their unique attributes and catalytic contributions. It also examines the effects of structural modifications, do**, and functional group integrations on the electrochemical properties and durability of graphene-based cathodes. Additionally, we address the thermal stability challenges of graphene derivatives at high SOFC operating temperatures, suggesting potential solutions and future research directions. This analysis underscores the transformative potential of graphene-based materials in advancing fuel cell technology, aiming for more efficient, cost-effective, and durable energy systems.

Enzyme biofuel cells (EBFCs) can convert chemical or biochemical energy in fuel into electrical energy, and therefore have received widespread attention. EBFCs have advantages that traditional fuel cells cannot match, such as a wide range of fuel sources, environmental friendliness, and mild reaction conditions. At present, research on EBFCs mainly focuses on two aspects: one is the use of nanomaterials with excellent properties to construct high-performance EBFCs, and the other is self-powered sensors based on EBFCs. This article reviews the applied nanomaterials based on the working principle of EBFCs, analyzes the design ideas of self-powered sensors based on enzyme biofuel cells, and looks forward to their future research directions and application prospects. This article also points out the key properties of nanomaterials in EBFCs, such as electronic conductivity, biocompatibility, and catalytic activity. And the research on EBFCs is classified according to different research goals, such as improving battery efficiency, expanding the fuel range, and achieving self-powered sensors. Full article
