| description | 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-containing nanofiber 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.
La présente invention concerne : une membrane électrolytique de polymère composite qui présente une excellente conductivité de protons, même dans des conditions de faible humidification et de basse température, un faible taux de changement dimensionnel, et d'excellentes résistance mécanique et stabilité chimique, et qui est capable d'atteindre un débit élevé et une excellente durabilité physique lorsqu'elle est utilisée dans une pile à combustible à polymère solide ; et un composite d'électrode à membrane et une pile à combustible à polymère solide utilisant la membrane électrolytique de polymère composite. Cette membrane électrolytique de polymère composite comporte une couche composite formée par combinaison d'un tissu non-tissé de nanofibres contenant du polyazole (A) et un électrolyte de polymère contenant un groupe unique (B), et est caractérisé en ce que le tissu non-tissé de nanofibres contenant du polyazole (A) est basique. |
