Beschreibung
Zusammenfassung:	Provided are a composite polymer electrolytic membrane that has excellent proton conductivity even under low-humidification and low-temperature conditions, a small dimensional change rate, and excellent mechanical strength and chemical stability, and that is capable of achieving a high output and excellent physical durability when being used in a solid polymer fuel cell; and a membrane electrode composite and a solid polymer fuel cell using the composite polymer electrolytic membrane. This composite polymer electrolytic membrane has a composite layer formed by combining a polyazole-containingnanofiber unwoven fabric (A) and an ionic-group-containing polymer electrolyte (B), and is characterized in that the polyazole-containing nanofiber unwoven fabric (A) is basic. 本发明提供即便在低加湿、低温条件下也具有优异的质子传导性、而且尺寸变化率小、机械强度和化学稳定性优异、并且在制成固体高分子型燃料电池时能够实现高输出、优异的物理耐久性的复合高分子电解质膜及使用其的膜电极复合体、固体高分子型燃料电池。该复合高分子电解质膜的特征在于，是具有复合层的复合高分子电解质膜，所述复合层是含有聚唑的纳米纤维无纺布(A)与含有离子性基团的高分子电解质(B)复合化而成的，所述含有聚唑的纳米纤维无纺布(A)为碱性。
