## Description

- description: In this presentation, membrane electrode assembly (MEAs) were fabricated
    by the decal method using Nafion115 or CSPPSU membranes and catalysts coated on
    PTFE sheets. The water electrolysis characteristics were investigated using a
    self-made water electrolysis apparatus from 80°C to 150°C. The WU and conductivity
    of the Nafion115 and CSPPSU membranes were 38%, 47mS/cm (80°C, RH90%) and 37%,
    12mS/cm (80°C, RH90%), respectively. The anode and cathode side electrodes (S=1cm2)
    were prepared by applying IrO2 (1 mg/cm2) and Pt/C (I/C=1) (Pt=1 mg/cm2) on PTFE
    sheets, respectively. The MEA was prepared by transferring the catalyst onto the
    membrane by hot pressing at 165°C or lower for 10 minutes. The cells were serpentine
    type, and the anode side was platinum coated. The anode supply water temperature
    was 80°C. Water supply rate is 2 ml/min. IV measurements were evaluated while
    increasing the Oven temperature from 80°C to 150°C. The characteristics of MEAs
    with Nafion115 and CSPPSU membranes showed an increase in current density and
    a decrease in membrane resistance and interface resistance with increasing cell
    temperature. The IV performance of the cell with CSPPSU membrane was comparable
    to that of the cell with Nafion115 membrane. These results suggest that CSPPSU
    membranes, which have a higher glass transition temperature than Nafion membranes,
    are expected to be applied to high-temperature water electrolysis.
