Abstract: An integrated thin film battery and fabrication method thereof is provided, in which a plurality of thin film batteries and thin film solar cells are formed in grooves formed on a substrate, to thereby secure stabilities of the thin film batteries and the thin film solar cells and provide a desired charging capacity and output voltage. The integrated thin film battery includes a substrate made of an electrical insulation material and whose one surface is etched to form a groove thereon; and a thin film battery including an anode, an electrolyte, a cathode, and anode and cathode current collectors respectively contacting the anode and cathode, for collecting current, which is formed on a groove formed on the substrate, for charging and discharging electrical energy.

Abstract: Disclosed is a method of preparing a platinum alloy electrode catalyst for DMFC using anhydrous metal chlorides, which method includes reducing platinum chloride and non-aqueous second metal chloride with boron lithium hydride (LiBH4) in a water-incompatible organic solvent in the nitrogen atmosphere to form a nano-sized particles of colloidal platinum alloy, and drying the platinum alloy particles without any heat treatment.
