  • STIRRING HOT PLATE
    Publication number: 20080047954
    Abstract: A stirring hot plate for simultaneously heating and stirring a mixture includes a phase controlled motor that spins magnets which couple to, and thereby spin, a stir bar within the mixture. In addition to spinning the magnets, the motor includes an operational mode in which the motor is rapidly braked thereby quickly spinning down the stir bar. The stirring hot plate also includes a visual indicator to the user that the platform is hot-to-the-touch that is especially effective when the stirring hot plate is not in use.

  • Separator plate for a fuel cell
    Patent number: 5503945
    Abstract: A separator plate for a fuel cell comprising an anode current collector, a cathode current collector and a main plate, the main plate disposed between the anode current collector and the cathode current collector. The anode current collector forms a flattened peripheral wet seal structure and manifold wet seal structure on the anode side of the separator plate and the cathode current collector forms a flattened peripheral wet seal structure and manifold wet seal structure on the cathode side of the separator plate. In this manner, the number of components required to manufacture and assemble a fuel cell stack is reduced.
