  • Patent number: 9799900
    Abstract: Disclosed is a fuel supplying apparatus, for a direct carbon fuel cell, which has improved output density by ensuring the flow properties of an anode medium. The fuel supplying apparatus for a direct carbon fuel cell comprises: a flow pipe which forms a flow path around a tube-shaped cell contained in an anode medium in which a carbon fuel is mixed; and a bubbling means which provides a gas from below the flow pipe to the inside of the anode medium and thus enables the anode medium to flow by the upward movement of the gas. Consequently, the carbon fuel is forcibly provided to the anode of the tube-shaped cell by the flow of the anode medium which is linked with the upward movement of the gas.

  • Patent number: 9711710
    Abstract: A specific region of a polylactic acid sheet is heated by a microwave. To allow the polylactic acid sheet to exhibit piezoelectricity in the thickness direction of the polylactic acid sheet, a high voltage is applied to the heated polylactic acid sheet in the thickness direction of the polylactic acid sheet, and thereby the screw axes of at least a part of the polylactic acid molecules are relatively aligned with the thickness direction. Then the polylactic acid sheet is rapidly cooled, and thereby the polylactic acid molecules are immobilized. The same step is executed for other regions of the polylactic acid sheet, and thereby piezoelectricity is imparted to a wide area of the polylactic acid sheet in the thickness direction. The resultant piezoelectric sheet is capable of exhibiting a high piezoelectricity in the thickness direction.
