## Description

- description: Sulfonated polyphenylsulfone (SPPSU) with a high ion exchange capacity
    (IEC) was synthesized using commercially available PPSU, and a large-area (16
     18 cm) CSPPSU membrane was prepared. In addition, we developed an activation
    process, in which the membrane was treated with alkaline and acidic solutions
    to remove sulfur dioxide (SO2), which forms as a byproduct during heat treatment.
    CSPPSU membranes obtained using this activation method had high thermal, mechanical
    and chemical stabilities. In I-ViR free studies for fuel cell evaluation, high
    performances, similar to those using Nafion, were obtained. In addition, from
    the hydrogen (H2) gas crossover characteristics, the durability is much better
    than that of a Nafion212 membrane. In the studies evaluating the long-term stabilities
    by using a constant current method, a stability of 4000 h was obtained for the
    first time. These results indicate that the CSPPSU membrane obtained by using
    our activation method is promising as a polymer electrolyte membrane.
