## Description

- description: We have developed a polymer electrolyte membrane using polyphenylsulfone
    (PPSU) as a hydrocarbon-based polymer as a non-fluorinated electrolyte membrane
    . A hydrocarbon-based polymer electrolyte ionomer was synthesized by sulfonating
    PPSU polymer at different temperatures and times to obtain an ionomer with high
    ion exchange capacity (IEC=3.5 meq/g, DS=2). The SPPSU electrolyte membrane was
    prepared by dissolving the SPPSU ionomer in an organic solvent, casting it on
    a glass plate at 60 °C using a coater device, and obtaining a crosslinked SPPSU
    (CSPPSU) membrane by a thermal process up to 250 °C in an oven. The final membrane
    was obtained by an activation process in an alkaline and acid aqueous solution
    (wet process) to remove remaining impurities in the crosslinked membrane. The
    physical and chemical properties of the obtained SPPSU ionomer and CSPPSU membrane
    were evaluated. In addition, an membrane electrode assembly (MEA) was produced
    using a CSPPSU membrane and a fuel cell evaluation was performed. These results
    allowed us to optimize the sulfonation and crosslinking conditions of the PPSU
    polymer.
