Abstract: A fuel cartridge and a fuel cell power generation system equipped with the fuel cartridge are disclosed. The fuel cartridge can include a hydrogen generation part, which generates hydrogen by reacting with an electrolyte solution, a liquid-gas separation membrane, which surrounds the hydrogen generation part and separates the generated hydrogen from the electrolyte solution and discharges the hydrogen to the outside, and a cap, which opens and closes the liquid-gas separation membrane. The fuel cartridge of the present invention can reduce an effect of electrolyte solution flowing backwards and generate hydrogen more efficiently by minimizing the loss of electrolyte solution.

Abstract: A hydrogen generating apparatus and a fuel cell power generation system. An aspect of the invention provides a hydrogen generating apparatus for generating hydrogen through a dissociation reaction of an aqueous solution using electrons formed by an ionization of a metal. The hydrogen generating apparatus can include a chamber, which contains the aqueous solution, and in one side of which an outlet is formed to discharge the hydrogen; and a membrane, which is formed inside the chamber adjacent to the outlet, and which selectively permits the passage of the hydrogen. With certain embodiments of the invention, the overflowing of reagents can be prevented, for higher efficiency in the fuel cell. Because of the improvement in efficiency of the fuel cell power generation system, the volume of the system can be reduced, allowing for easier application to mobile devices.

Abstract: A hydrogen generating apparatus is disclosed, which can provide a constant amount of hydrogen regardless of its orientation. The hydrogen generating apparatus can include an electrolyte bath, which contains an electrolyte solution; a free-moving first electrode, which is positioned inside the electrolyte bath, and which generates electrons; a free-moving second electrode, which is positioned inside the electrolyte bath, and which receives the electrons to generate hydrogen; a spacer positioned between the first electrode and the second electrode; and a control unit, which is connected with the first electrode and the second electrode, to control an amount of electrons traveling from the first electrode to the second electrode.

Abstract: A hydrogen generating apparatus can include an absorbent layer that absorbs an aqueous solution, a metal membrane deposited on either side of the absorbent layer such that the absorbent layer is interposed between the metal membranes, and a support layer formed on one side of one of the metal membranes that transports hydrogen generated by a reaction between the aqueous solution and the metal membrane. A batch type reaction may thus be implemented between the aqueous solution and the metal membranes, so that the reaction can be controlled to provide an even rate of hydrogen generation. Possible disturbances to the reaction resulting from by-products can be prevented, and since there is no additional equipment required, the volume and weight of the fuel cell power generation system can be reduced, and the extra power consumption by the additional equipment can be avoided.

Abstract: A fuel cell and a method of manufacturing the fuel cell are disclosed. A method of manufacturing a fuel cell by electrically connecting a first cell and a second cell that are coupled over both sides of a membrane with a predetermined gap between the first cell and the second cell, where the first cell and the second cell each has an anode on one side and a cathode on the other side, may include perforating a hole in the membrane between the first cell and the second cell, and electrically connecting the anode of the first cell with the cathode of the second cell through the hole using a conductive member. This method does not entail unnecessary increases in volume or complicated flow paths, and the method can reduce electrical resistance while simplifying the peripheral equipment.

Abstract: A direct alcohol fuel cell (DAFC) that uses methanol or ethanol as a fuel includes a membrane electrode assembly in which an anode, an electrolyte membrane, and a cathode are stacked, a fuel chamber in which alcohol is stored, and a fuel supply system that supplies the alcohol to the anode from the fuel chamber, wherein the fuel supply system comprises: a spreader that allows the alcohol received from the fuel chamber to be uniformly distributed with respect to an entire surface of the anode; a supply control unit that controls the supply of the alcohol from the fuel chamber to an inlet of the spreader; and a buffer installed between the spreader and the anode to limitedly pass alcohol towards the anode. Accordingly, the DAFC can reduce unnecessary fuel consumption during a shutdown operation and can stably and uniformly supply fuel during a normal operation.

Abstract: Disclosed is a method of manufacturing a build-up printed circuit board, in which the circuit of a build-up printed circuit board including a core layer and an outer layer is realized by forming the metal seed layer of the core layer using a dry process, consisting of ion beam surface treatment and vacuum deposition, instead of a conventional wet process, including a wet surface roughening process and electroless plating. When the wet process is replaced with the dry process in the method of the invention, the circuit layer can be formed in an environmentally friendly manner, and as well, all circuit layers of the substrate including the core layer and the outer layer can be manufactured through a semi-additive process. Further, the peel strength between the resin substrate and the metal layer can be increased, thus realizing a highly reliable fine circuit.
