Abstract: A method of manufacturing a fuel cell catalyst can include a method of manufacturing a carbon carrier for a fuel cell catalyst, in which the carbon carrier can have an improved binding force to a catalytic metal and improved carbon durability. The carbon carrier can be coated with a carbon layer highly doped with heteroatoms. The carbon layer can be formed by uniformly compounding a conductive polymer containing the heteroatoms with the carbon carrier and heat-treating the compounded mixture.

Abstract: A refrigerator for drinks is provided. The refrigerator may have an open hole that is open upward, so a drink container may be inserted in an erect state in a cabinet through the open hole. An insertion guide connected to the open hole may be disposed in the cabinet and the width of the insertion guide may change in a height direction. Accordingly, a drink container may be guided by the insertion guide when being inserted into or taken out of the refrigerator for drinks.

Abstract: A refrigerator for drinks is provided. The refrigerator has an open hole that is open upward to allow a drink container to be inserted in an erect state in a cabinet through the open hole. An insertion guide connected to the open hole is disposed in the cabinet and the width of the insertion guide changes in a height direction. Accordingly, a drink container is guided by the insertion guide when being inserted into or taken out of the refrigerator for drinks.

Abstract: A refrigerator for drinks may include a cabinet and a cooling guide transmitting coldness to a drink container stored in an erect state in the cabinet. Several coolers may be disposed for cooling guides and may cool the cooling guides, respectively, and dispenser nozzles may be disposed to be exposed outside the cabinet, whereby drinks may be dispensed. A surface of a cooling block facing a thermoelectric element of the cooler and a surface of the cooling block facing the cooling guide may have different areas.

Abstract: A refrigerator includes a cabinet, a cooling guide transmitting coldness to a drink container stored in an erect state in the cabinet, a cooler located in the cabinet to cool the cooling guide, and a dispenser nozzle disposed to be at least partially exposed outside the cabinet. The cooler includes a thermoelectric element and a cooling block having a surface facing the thermoelectric element of the cooler and a surface of the cooling block facing the cooling guide, where the surfaces have different areas.

Abstract: A catalyst for electrochemical reaction and a method of preparing the same are disclosed. Particularly, a heat treatment method is disclosed for oxidizing or reducing only a specific active material in a synthesized catalyst in which two or more active materials are mixed.

Abstract: A method for producing a catalyst for an electrochemical reaction that can be sized into fine particles while having a high specific surface area by using a carbon-based spacer in the catalyst synthesis process includes preparing a mixture by mixing a carbon-based spacer and a catalyst precursor and heat-treating the mixture.

Abstract: A refrigerator for drinks is provided. The refrigerator may include a cabinet having a storage compartment therein, and a dispenser nozzle disposed to be at least partially exposed outside the cabinet. A pump connection line being able to increase pressure in a drink container by delivering high-pressure air into the drink container and a tank connection line preventing oxidation of the drink in the drink container by delivering an unreactive gas into the drink container may be disposed in the cabinet. Accordingly, two functions of discharging a drink and preventing oxidation may be individually performed, so consumption of an unreactive gas may be reduced.
