Beschreibung
Zusammenfassung:	A proton conducting inorganic material having a layered structure in which a sulfonic acid group-containing moiety having proton conductivity is introduced in between the layers of an inorganic material having a nano-sized interlayer distance such that the sulfonic acid group-containing moiety is directly bound to the inorganic material via an ether bond. A polymer nano-composite membrane including the product of a reaction between the inorganic material having the sulfonic acid-containing moiety with a proton conducting polymer, and a fuel cell adopting the same, wherein the polymer nano-composite membrane has a structure in which a proton conducting polymer is intercalated between the layers of the proton conducting inorganic material having a layered structure, or a structure in which the product of exfoliating the proton conducting inorganic material having a layered structure is dispersed in a proton conducting polymer. The polymer nano-composite membrane can have a controllable degree of swelling in a methanol solution, and the transmittance of the polymer nano-composite membrane can be reduced.
