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 it cylindrical flow path in the vertical direction 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 vertical flow of the gas. Consequently, the anode medium is provided to the anode of the tube-shaped cell by the flow.

Abstract:
The present invention relates to a controlled expansion flexible metal substrate material and to a production method therefor. In the present invention, an electrocasting method is used in order to produce a metal substrate material which comprises a controlled expansion alloy and has a textured structure and a wide width. Also, the flexible metal substrate material of the present invention can be used as the substrate for a silicon thin-film solar cell since the Fe—Ni alloying compositional ratio is controlled in such a way that the thermal expansion coefficient approximates that of silicon. The present invention is devised in such a way that the optical pathway is extended and the photoelectric conversion efficiency is improved since a textured structure is provided on the surface of a flexible metal substrate material by forming a textured structure on the surface of a plating drum used as a plating cathode or anode used in an electrocasting method.
