Title:
POLYELECTROLYTE MOLDED BODY, AND POLYELECTROLYTE MEMBRANE, ELECTROLYTE MEMBRANE WITH CATALYST LAYER, MEMBRANE ELECTRODE ASSEMBLY, SOLID POLYMER-TYPE FUEL CELL, AND WATER ELECTROLYSIS-STYLE HYDROGEN PRODUCTION DEVICE IN WHICH SAID POLYELECTROLYTE MOLDED BODY IS USED
Document Type and Number:
WIPO Patent Application WO/2022/202596
Kind Code:
A1
Abstract:
A polyelectrolyte molded body that has superior proton conductivity as well as superior mechanical strength and chemical stability is achieved by a polyelectrolyte molded body that is characterized in that, among the mean period sizes of a phase separation structure as observed by small-angle X-ray scattering, the mean period size in air and the mean period size in water satisfy the following expression: mean period size in water / mean period size in air ≤ 2.20.
