| description | The present invention provides a composite polymer electrolyte membrane that has a high proton conductivity even under low-humidity, low-temperature conditions, has a reduced dimensional change rate, has a high mechanical strength and high chemical stability, and serves to produce a solid polymer electrolyte fuel cell with a high output and high physical durability, and also provides a membrane electrode assembly and a solid polymer electrolyte fuel cell containing the same. This composite polymer electrolyte membrane contains a composite layer composed mainly of a polyazole-containing nanofiber nonwoven fabric (A) and an ionic group-containing polymer electrolyte (B), the polyazole-containing nanofiber nonwoven fabric (A) being basic. |
