    摘要： Disclosed is a method for producing an electrode catalyst for a fuel cell, which comprises a Ru-containing metal microparticle supported on an electrically conductive carbon carrier, wherein M2RuX6 [M=at least one member selected from H, Li, Na, K and NH4; X=at least one member selected from Cl, Br, I and NO3] is used as a precursor of Ru. It becomes possible to produce an electrode catalyst for a fuel cell, which is improved in the methanol oxidation activity per mass or surface area of the catalyst compared with a conventional Pt- and Ru-carrying carbon catalyst prepared by using a Ru raw material having an average valency of 3.

    摘要： Disclosed is an electrolyte membrane-electrode assembly for direct methanol fuel cells, wherein a solid polymer electrolyte membrane is held between a pair of electrodes each composed of a catalyst layer coated over and/or impregnated in a porous supporting body. This electrolyte membrane-electrode assembly for direct methanol fuel cells is characterized in that the solid polymer electrolyte membrane is obtained by irradiating a resin membrane with radiation and graft-polymerizing a radically polymerizable monomer. The electrolyte membrane-electrode assembly for direct methanol fuel cells is further characterized in that the catalyst layer of the anode electrode comprises a catalyst, wherein platinum group metal or platinum-containing alloy particles having a particle size of 5 nm or less are supported by carbon particles, and a solid polymer electrolyte, and the noble metal amount in the catalyst layer of the anode electrode is not more than 5 mg/cm2. By using such a catalyst, there can be obtained a direct methanol fuel cell wherein high output is achieved by using high methanol concentration.

    摘要： This invention provides a process for producing an electrode catalyst for a fuel cell, comprising a first support step of producing metallic fine particles having an average particle diameter of 0.1 to 1.5 nm provided at regulated particle intervals on an electroconductive carbon carrier, and a second support step of growing a metal identical to or dissimilar to the metal using the metallic fine particles as a nucleus. In the first support step, the metallic fine particles are supported by an immersion method. The above constitution can provide an electrode catalyst for a fuel cell, which has a high level of percentage support, has a high level of dispersibility, and has improved methanol oxidation activity per weight of the catalyst. Further, when treatment in an atmosphere containing hydrogen is carried out at a low temperature below 100° C., the methanol oxidation activity per active surface area can be improved without lowering the active area.

    摘要： An optical waveguide substrate is prepared by forming grooves in a silicon substrate in accordance with the pattern of a desired waveguide device, thermally oxidizing the silicon substrate to form a peripheral quartz layer surrounding the grooves, burying in the grooves a doped quartz glass layer having a higher refractive index, abrading the surface of the resulting structure to be flat, and forming on the flat surface a glass layer having a lower refractive index. An optical waveguide substrate featuring no distortion of the core pattern, little warp, and a low loss can be produced in a simple manner.
