【 摘 要 】

In this study, organic-inorganic composite electrolyte membranes are developed for a novel water-absorbingporous electrolyte water electrolysis cell. As the materials of the composite electrolyte membrane, 80 wt% of a proton-conductingnano zeolite (H-MFI) as an electrolyte and 20 wt% of poly(vinyl alcohol) (PVA) as a cross-linkable matrix are used.The nano zeolite is prepared by a milling process. The nano zeolite-PVA composite membrane precursors are prepared byspraying onto a substrate, followed by cross-linking. The resulting nano zeolite-cross-linked PVA composite films are thenevaluated for their properties such as proton conductivity as electrolyte membranes for the water-absorbing porous electrolytewater electrolysis cell. It is confirmed that conventional materials such as zeolites and PVA can be used for the water electrolysisas an electrolyte.
