    Abstract: PROBLEM TO BE SOLVED: To provide methods of manufacturing catalyst and fuel cell suppressing aggregation of particles in a hot burning process and elution of metal atoms under a strong acid, and the fuel cell. SOLUTION: The method of manufacturing catalyst includes a first process of forming a coating layer made of an inorganic oxide coating catalyst precursor particles consisting of metal atoms (for example, Pt, Ru), a second process of burning the catalyst precursor particles with the coating layer formed, and a third process of removing the coating layer. The first process includes (a) the process of chemically or physically bonding a surface modifying agent having a hydrophobic group to the catalyst precursor particle to modify its surface, (b) the process of forming a hydrophobic layer with a hydrophobic group of a surfactant and the hydrophobic group of the surface modifying agent, and (c) the process of coating the hydrophobic layer with the inorganic oxide to form the coating layer. For example, Pt, Ru are alloyed. The inorganic oxide is, for example, a silicon dioxide having a high melting point and dissolvable in an acid. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PURPOSE:To provide a floating component as a parts supply device, which can perform the positioning at the high accuracy, without generating damage on a parts and braking a parts at the time of supplying parts. CONSTITUTION:A floating component is provided with a fixed block having a fixed stem 1 and a floating block having a floating stem 9. The floating stem 9 is fixed by multiple air cylinders 2, 3 provided in the fixed stem 1 and the air. Since the floating stem 9 can be moved in a predetermined direction and in the direction of an angle of rotation freely, the generation of damage on a parts at the time of supplying parts can be prevented.
