Sulfonated poly(ether ether ketone) (SPEEK) was blended with poly(ether sulfone) (PES) to make solid polymer electrolyte (SPE) membranes for hydrogen production via water electrolysis. The blend membranes were characterized in terms of proton conductivity and the swelling degree in water. Membrane electrode assemblies (MEA), with Ir anode and Pt cathode at the two side of the blended membrane, were prepared by a decal method. The effect of hot pressing conditions in fabricating the MEA and the influence of ionomers in the catalyst layers were investigated. The MEA, with an effective area of 4 cm2, were tested using a single cell water electrolysis test stand. An electrolytic current of 1655 mA/cm2 were obtained at 2 V and 80 °C with the SPEEK based MEA and under suitable fabrication conditions. The experimental results suggest that SPEEK/PES blend membrane could be an alternative to costly perfluorosulfonate membranes in SPE water electrolysis for hydrogen production.
