TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The conductive filler comprises graphite powder, carbon fiber, expanded graphite, carbon black, coke and/or carbon nanotube. The conductive filler is a mixture of graphite powder (65-90 wt.%), carbon fiber (30-5 wt.%) and expanded graphite (5-10 wt.%). The rheology modifier is magnesium oxide.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The free radical initiator comprises tert-butyl perbenzoate or perbenzoic acid. (I) further comprises a rheology modifier or a releasing agent. The releasing agent comprises fluorine wax, metal soap, hydrocarbon wax, polyethylene, amide wax, fatty acid, fatty alcohol, or fatty ester.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The copolymer of vinyl terminated rubber-styrene is copolymerized in the presence of a free radical initiator from vinyl terminated rubber (1 to 90 wt.%) and styrene (10-99 wt.%). The copolymer of vinyl terminated rubber-styrenedivinyl benzene is copolymerized in the presence of a free radical initiator from vinyl terminated rubber (1-20 wt.%), styrene (60-98 wt.%) and divinyl benzene (1-20 wt.%). The copolymer of styrene-divinyl benzene is copolymerized in the presence of a free radical initiator from styrene (90-99 wt.%) and divinyl benzene (1-10 wt.%). The vinyl terminated rubber comprises polybutadiene, natural rubber, polyisopropylene, styrene-butadiene rubber, butyl rubber, nitrile rubber, ethylene-propylene rubber, polychlorobutadiene, polyvinyl chloride, polysiloxane and/or fluorinated rubber. The vinyl terminated rubber is polymerized from acrylnitrile and butadiene. The vinyl terminated rubber has a weight average molecular weight of 1000-10000, preferably 4500-5500. EXAMPLE - A graphite oxide (200 g) was placed in a stainless steel tank (3 l capacity), then send into a furnace at 1000 degrees C for 60 seconds to obtain expanded graphite. Vinyl terminated rubber-styrene-divinyl benzene (200 g), divinyl benzene (50 g), styrene (750 g), tert-butyl perbenzoate (30 g) and fluorine wax (30 g) were added in a beaker, and mixed into a solution. The mixer solution was stirred for 10-20 minutes. The solution was fed with graphite powder, carbon fiber (200 g) and expanded graphite (200 g) into the mixture, kneading by Masticator (high-strength stirring blades) for 60 to 90 minutes and worked up to give bipolar plate.
