    摘要： A monopolar membrane electrode assembly (MEA) for a fuel cell, for example, includes: an electrolyte membrane; anode and cathode electrodes formed on opposite surfaces of the electrolyte membrane, respectively; current collecting bodies that form electrical paths of electricity generated from an electricity generation reaction between the anode and cathode electrodes and the electrolyte membrane; and sensing elements to measure changes in operation state conditions during electricity generation and electrical connection. Since temperature and fuel concentration in the monopolar MEA having the above structure are detected on a real time basis, appropriate action can be taken whenever an abnormal operation thereof is detected.

    摘要： A fuel cell stack induces smooth current collection and liquid or gas flow without using a heavy bipolar plate. The fuel cell stack includes: a membrane and electrode assembly (MEA) in which an electrolyte membrane is disposed between a cathode electrode and an anode electrode; a current collector disposed in the MEA to form an electrical path with an adjacent MEA; and a non-conductive separation plate disposed between the MEA and the adjacent MEA, the non-conductive separation plate forming flow channels to supply a liquid or gas to the cathode electrode and the anode electrode. A fuel cell stack structure having the above structure is simple and lightweight as the MEA includes a thin and lightweight non-conductive polymer separation plate and a current collector to connect adjacent MEAs.

    摘要： A mesoporous carbon is prepared by mixing a carbon precursor, an acid, and a solvent to obtain a carbon precursor mixture; impregnating an ordered mesoporous silica (OMS) with the carbon precursor mixture; carbonizing the impregnated OMS at 800 to 1300° C. by irradiating microwave energy with a power of 100 to 2000 W thereon to form an OMS-carbon composite; and removing the mesoporous silica from the OMS-carbon composite. The method of preparing a mesoporous carbon can significantly reduce a carbonization time by carbonizing a carbon precursor using microwave energy in a silica template compared to a conventional method using a heat treatment. A supported catalyst and a fuel cell include the mesoporous carbon.

    摘要： A method of preparing a supported catalyst, the method comprising mixing a first catalytic metal precursor and a first solvent to obtain a first catalytic metal precursor mixture; mixing a carbon support for catalyst and the first catalytic metal precursor mixture, and drying the mixture to obtain a primary supported catalyst precursor; subjecting the primary supported catalyst precursor to a hydrogen reduction heat treatment, to obtain a primary supported catalyst; mixing the primary supported catalyst and a polyhydric alcohol to obtain a primary supported catalyst mixture; mixing a second catalytic metal precursor and a second solvent to obtain a second catalytic metal precursor mixture; mixing the primary supported catalyst mixture and the second catalytic metal precursor mixture to obtain a secondary supported catalyst precursor mixture; and adjusting the pH of the secondary supported catalyst precursor mixture, and then heating the secondary supported catalyst precursor mixture to obtain a supported catalyst, a supported catalyst prepared by the method, an electrode comprising the supported catalyst, and a fuel cell including the electrode are provided. A supported catalyst having a desired amount of loaded catalytic metal particles can be obtained by preparing a primary supported catalyst containing catalytic metal particles that are obtained by a primary gas phase reduction reaction of a portion of the final loading amount of catalytic metal, and reducing the remaining portion of the catalytic metal by a secondary liquid phase reduction reaction. The supported catalyst contains catalytic metal particles having a very small average particle size, which are uniformly distributed on a carbon support at a high concentration, and thus exhibits maximal catalyst activity. A fuel cell produced using the supported catalyst has improved efficiency.
