SPES was successfully used as PEM for hydrogen production through methanol electrolysis.
SPES membrane based MEA exhibits current density of 0.802 A/cm2 at a cell voltage of 1.2 V at 80 °C.
SPES based PEMEC shows improved hydrogen production and good durability.
SPES solid electrolyte membrane could be an effectual substitute to expensive Nafion membranes.
