## Description

- description: "Aiming to achieve carbon neutrality by 2050, safe electricity storage
    and utilization technologies using renewable energy are required. To achieve these
    technological developments, each component needs to have high performance. In
    particular, high performance catalysts and ion exchange polymer materials are
    key for fuel cells, water electrolysis, and redox flow batteries. Fluorine-based
    electrolytes such as Nafion are used as ion exchange polymer electrolytes, but
    the development of alternative electrolytes has attracted attention due to PFAS
    regulations. We are researching hydrocarbon-based SPPSU ionomers as non-fluorine-based
    electrolytes. \r\nSeveral SPPSU ionomers with high IEC were synthesized from PPSU
    polymer and monomer. The SPPSU ionomers from PPSU polymer had a high IEC value
    of 3.6 meq/g. The SPPSU ionomers synthesized from monomers had an even higher
    IEC value of 5.6 meq/g. These IEC values are higher than the IEC of Nafion ionomer
    (approximately 1.0 meq/g), and they are expected to be used as hydrocarbon ionomers.
    \r\nThe mechanical properties of the SPPSU ionomer synthesized from the polymer
    (IEC=3.6 meq/g) were more rigid than those of the SPPSU ionomer synthesized from
    the monomer (IEC=5.6 meq/g). The mechanical properties of the SPPSU ionomer synthesized
    from the monomer were similar to those of Nafion, but the youngs modulus was two
    times higher. The conductivity of the SPPSU ionomer synthesized from the monomer
    at 120°C and RH40% was about four times higher than that of Nafion. In this presentation,
    we will report on the physicochemical properties of the SPPSU ionomers with high
    IEC values."
