SOLID STATE PROTON CONDUCTOR SYSTEM DERIVED FROM HYBRID COMPOSITE INORGANIC-ORGANIC MULTICOMPONENT MATERIAL

摘要

The present invention provides a composition comprising: (i) a polysesquioxane matrix comprising a sesquioxane residue comprising a metal element; (ii) hydrophilic components; And (iii) a pros-conductive component. The metal element may be silicon, aluminum, titanium, zirconium, germanium or a mixture of two or more thereof. The hydrophilic component can comprise an imidazole residue, a pyrazole residue, a benzimidazole residue, a silanol residue, a cyclodextrin, or two or more thereof, and the hydrophilic component can be covalently linked to the polysesquioxane matrix. The proton-conducting component may comprise an inorganic Bronsted acid residue. The polysesquioxane compositions include proton exchange membranes in fuel cells; Components of the membrane electrode assembly; Or as a sensor assembly in a potentiometer sensor.
