TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The assistant proton conduction matter is selected from one or more of SiO2, silicon dioxide, zirconium oxide, titanium dioxide, boron phosphate, zirconium orthophosphate, zirconium hydrogen phosphate, tungestophosphoric acid, cesium- hydrogen-sulfate, H-mordenite, H-montmorillonite, cesium- hydrogen-phosphate, alpha-zirconium phosphate, cerium phosphates, titanium (II) monohydrogen phosphate or zirconium hydrogen bis(triphosphate). The mass ratio of the matters to the perfluorinated ion exchange film is 0.5-50:100 with diameter 0.001-5 microns. The high valent metal compound is selected from the complex salt of nitrate, sulfate, carbonate, phosphate, acetate or their mixture of the highest valence state or middle valence state of the element. The high valence metal compound is selected from cyclodextrin, crown ether, acetylacetone, nitrogenous crown ether and nitrogenous heterocyclic ring, ethylenediaminetetraacetic acid, dimethylformamide or dimethyl sulfoxide complex compound of the highest valence state or middle valence state of the element. The high valence metal compound is selected from hydroxide of the highest valence state or middle valence state of the element. The element of the high valence metal compound is selected from iridium, yttrium, manganese, ruthenium, vanadium, zinc or lanthanum. The metal compound is 0.001-5% of the mass of the perfluorinated ion exchange film. The high valence metal compound is selected from perovskite structured oxide of the highest valence state or middle valence state of the element. The perovskite structured oxide of formula CexTi1-xO2 (VI), Ca0.5La0.27TiO3 (VII), La(1-y)CeyMnO3 (VIII) or La0.7Ce0.15Ca0.15MnO3 (IX).x=0.25-0.4; andy=0.1-0.4.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The reinforcing fiber which is used as reinforcer is selected from glass fiber e.g. alkali resistant glass fiber or alkali-free glass fiber, fluorocarbon fiber e.g. polytetrafluoroethylene fiber or fluorinated ethylene propylene fiber, ceramic fiber e.g. natural flint clay or aluminium silicate fiber, mineral fiber e.g. quartz fiber, carborundum fiber or basalt fiber, oxide fiber or the combination fibers. The diameter of the fiber is 0.005-5 microns, the length is 0.05-3mm and the mass ratio of the fiber to the perfluorinated ion exchange film is 0.5-50:100.
