Abstract: The present invention relates to a nano-structured metal-carbon composite and applications thereof, and more specifically, to a nano-structured metal-carbon composite obtained by consecutively impregnating a transition metal precursor and a carbon precursor in a nano frame and reacting the precursors at high temperature. In the metal-carbon composite of the present invention, metal is orderly polydispersed with less than 1 nanometer within a mesoporous carbon, and metal is chemically combined with carbon. Therefore, the metal-carbon composite is useful for electrocatalyst of fuel cells.

Abstract: The present invention provides an apparatus for preparing sterilizing water, which comprises an electrolyzer wherein an anode chamber (10) and a cathode chamber (20) partitioned by an ion exchange membrane (40) form a unit cell (A), being alternately arranged and successively equipped with close relation; water inlets (61, 62) and water outlets (71, 72) are provided on the end plate (60, 70) at both ends of the electrolyzer; said anode chamber (10) and cathode chamber (20) having circulative openings at the vicinity of each edge at both sides centered from anode plate (11) and cathode plate (21), of which two circulative openings of diagonal direction among them have plural passages of fan-shape, in order for water introduced through the openings to pass through the passages to rapidly go through each electrode; and a gap-control gasket (30) and a gasket for preventing leakage of electrolyte (31) having plural horizontal members are provided at the center to form an anode reaction chamber (13) and a cathode r
Abstract: An apparatus and method of producing water for deodorization and cleaning applications is disclosed. In the apparatus or an electrolyzer, anode and cathode units are alternately arranged and are separated from each other by ion exchange membranes, and individually form a unit cell. Two end plates are attached to both ends of the electrolyzer. The inlet end plate has two water inlets, while the outlet end plate has two water outlets. In an electroanalysis of water in the apparatus, the current for the apparatus is set to a level of not higher than 100 A, while the voltage for the apparatus is set to a level of not higher than 100 V. In addition, the finally processed water of this invention has an acidity (pH) ranged from 2.0 to 12 and an oxidation/reduction electric potential ranged from -900 to +1180.
