Special Issue Information

Dear Colleagues,

The commercialization of fuel cells is mainly hampered by the high cost of platinum, which is responsible for catalyzing fuel cell electrochemical reactions. To date, the different lines of research in fuel cells seek to address the challenges of reducing the Pt content, water management, thermal management, and to develop efficient electrocatalysts for enhanced ORR. All the above, designing efficient electrode architecture requires urgent action, because the present fuel cell membrane electrode assemblies (MEAs) experience severe incompatibilities between the materials utilized for electrodes and membranes. Therefore, this Special Issue primarily focuses on the nano-engineering of electrocatalysts materials, namely, perovskites, metal organic framework, core-shell, transition metal-binding organic materials, Pt alloying and new alloy catalysts for advanced MEAs with exceptional power densities and long-term stability.

Direct ethanol fuel cells (DEFCs) have emerged as promising and advanced power systems that can considerably reduce fossil fuel dependence, and thus have attracted worldwide attention. DEFCs have many apparent merits over the analogous devices fed with hydrogen or methanol. As the key constituents, the catalysts for both cathodes and anodes usually face some problems (such as high cost, low conversion efficiency, and inferior durability) that hinder the commercialization of DEFCs. This review mainly focuses on the most recent advances in nanostructured catalysts for anode materials in DEFCS. First, we summarize the effective strategies used to achieve highly active Pt- and Pd-based catalysts for ethanol electro-oxidation, including composition control, microstructure design, and the optimization of support materials. Second, a few non-precious catalysts based on transition metals (such as Fe, Co, and Ni) are introduced. Finally, we outline the concerns and future development of anode catalysts for DEFCs. This review provides a comprehensive understanding of anode catalysts for ethanol oxidation in DEFCs. Full article
