MOF-polymer composite membranes to enhance proton conductivity in fuel cells


Nafion (a perfluorosulfonic acid membrane) is widely used in fuel cells to conduct protons, but Nafion membranes are prone to rapid dehydration at low humidity, which results in a loss of conductivity. To overcome this problem, scientists in China have made a metal-organic framework (MOF) containing protonated tertiary amines as intrinsic proton carriers and hydrogen-bonding chains as proton-conducting pathways. A series of composite membranes with different contents of MOF crystals were prepared by blending MOF submicrorods with a polymer for the exploration of further applications of MOFs in fuel cells under low humidity. The MOFs displayed low-humidity proton conductivity.

    Zeolites for efficient oil-water separation

    Scientists in China have used zeolite-coated mesh films for gravity-driven oil-water separation. The superhydrophilicity and underwater superoleophobicity of the zeolite’s surface allow the highly efficient separation of various oils. Unlike other oil-water separation membranes based on sup ... more

    Graphene Rainbow

    Butterfly wings, rose petals and many other natural surfaces repell water strongly; they are superhydrophobic. Such surfaces have a hierarchical structure on the micrometer or nanometer scale. Their attractive properties and spectacular iridescent colors have triggered a group led by Hong-B ... more

    Electroluminescence devices

    A highly efficient, low driving-voltage, phosphorescent material for electroluminescence devices has been developed by scientists in Asia. Zhaomin Hou from RIKEN Advanced Science Institute, Japan and colleagues from Jilin University, China, have synthesised an iridium complex with highly e ... more
