“…Fuel flow rate and concentration are two parameters considered in the development of mathematical models in the research of De Souza et al 109 The yield of the benchmark is limiting current density and is consistent with observations in the literature. Dutta et al 110 combined three different states of element as support material in the DEFC catalyst; the fabricated catalyst has transitional metal/metal oxide/hydroxide (Ni/NiO/Ni (OH) 2 ). Ternary nano‐alloy catalysts were prepared by facile one‐pot synthesis.…”

Progress and challenges: Review for direct liquid fuel cell

Summary Direct liquid fuel cell (DLFC) is one of the leading fuel cell types due to their great features of superior energy density, modest configuration, small size in fuel container, immediate boosting, and effortless storage and carriage. Commercially used liquid fuel types are prepared using alcohols, such as methanol or ethanol, glycol, and acids. DLFCs face great challenges although they are potentially far‐reaching depending on the expensive catalysts and the use of high‐loading catalyst. More questions that should be addressed to ensure excellent DLFC performance include cathode flooding, fuel crossover, numerous side yield production, fuel security, and unverified elongated‐duration robustness. Further studies need to be carried out to ensure the continuous improvement of the quality of DLFCs' performance and their penetration in the commercial market. To date, direct liquid fuel cells made of methanol and ethanol have been successfully produced in commercial scale, but other types of DLFCs are still under study. In this review, introduction to DLFC will be discussed by covering work and commercialization as well as recent progress and challenges encountered.

In order to provide solutions for the pollution caused by nitrogen-containing wastewater and the shortage of fossil fuels, it is urgent to design highly performing bifunctional catalysts for the urea oxidation reaction (UOR) and hydrogen evolution reaction (HER). Herein, asok-like Ni-NiO-Mo0.84Ni0.16/NF hybrids are synthesized via hydrothermal and calcination methods. They exhibit superior catalytic activities for UOR (1.33 V at 50 mA cm–2), higher than the ever-reported NiMo-based catalysts, and for HER (0.069 V at 50 mA cm–2). Furthermore, the decline in catalytic performance is negligible after operating for 60 h at 250 mA cm–2. We suppose that the reason could be attributed to the special asok-like structure, a self-supported structure formed with 3D nickel foam (NF) and the three-phase hybrids. This work proposes a new strategy for the preparation of asok-like NiMo-based cost-effective catalysts, highly performing for both nitrogen-containing wastewater treatment and large-scale H2 production.
