Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Control-oriented modeling and exploration of hygrothermal characteristics of air-cooled proton exchange membrane fuel cell

Energy Reports, 2022
Achieving high output performance of air-cooled proton exchange membrane fuel cells relies on appropriate temperature and water content management. However, the open-cathode structure of the fuel cell stack leads to the coupling of thermal-water controls

Cation–Anion Co‐doping Enables Acid‐Stable MnO2 Anodes for Proton Exchange Membrane Water Electrolysis

Small Science
Developing acid‐stable, earth‐abundant oxygen evolution catalysts remains a central challenge for proton exchange membrane water electrolyzers (PEM‐WE), due to catalyst degradation via overoxidation under strongly anodic conditions.
