Document Type and Number:

Japanese Patent JP7371680

Kind Code:

B2

Abstract:

To provide a polymer electrolyte membrane which can be applied to a polymer electrolyte water electrolyzer, and is capable of producing a polymer electrolyte water electrolyzer having a low electrolytic voltage and excellent in hydrogen gas recovery efficiency, as well as a membrane electrode assembly and a polymer electrolyte water electrolyzer obtainable by using it.The polymer electrolyte membrane of the present invention contains a polymer electrolyte, of which the hydrogen gas permeation coefficient under the conditions of a temperature of 80°C and a relative humidity of 10%, is at most 2.4 × 10^-9 cm³·cm/(s·cm²·cmHg), wherein the membrane resistance value under the conditions of a temperature of 80°C and a relative humidity of 50%, is from 50 to 150 mΩ·cm².
