  • Fuel cell system
    Patent number: 8247125
    Abstract: The invention relates to a fuel cell stack (10) of a fuel cell system that is to be hermetically sealed off from the environment after operation is ended so that only a finite amount of air oxygen remains in the fuel cells, thus preventing the fuel cells from excessively aging. According to the invention, locking means (26, 28; 32, 34) are provided that are disposed on or in an end plate (14) or distributor plate of the fuel cell stack (10). The locking means (26, 28; 32, 34) are therefore thermally coupled to the end plate (14) and may freeze up at cold ambient temperatures. In a preferred embodiment, the locking means (26, 28; 32, 34) comprise an elastomer body (32, 34) able to cover and uncover a channel (44, 46) in the plate (14).

  • Method and apparatus for producing a composite component
    Patent number: 8241552
    Abstract: In a method and apparatus for producing a composite component, a tubular hollow section blank is placed into a die cavity of a combination tool comprising an inner high-pressure shaping tool and an injection-molding tool. The combination tool is filled with a fluid in such a way that the blank is wetted from the inside by the fluid, and the ends of the combination tool are sealed by two axial molding plugs. The filled blank is then expanded under pressure . The finished hollow section is plastic-coated in the same tool. The hollow section is emptied after shaping in the sealed state, at least until it is no longer dripping, the pressurized fluid being expelled under pressure from the hollow section through at least one discharge channel formed in the axial molding plugs.
