摘要： A method of manufacturing a separator for a polymer electrolyte fuel cell in which the specific resistance is small, and the coefficient of thermal conductivity and the gas shielding property are high and have high strength. The sintering material comprises a phenol resin coated to the surface of a powder of carbon, and the plate is a metallic plate having plating on both surfaces. After the metallic plate is arranged in a mold provided with grooves, the sintering material is filled to both sides of the metallic plate, and then they are heated and sintered. The separator for a fuel cell becomes homogeneous, and, as a result, the gas shielding property rises with high strength, because phenol resin has been uniformly distributed in the sintering material. Moreover, because oxides are not generated on the surfaces of the separator by sintering, the specific resistance will be relatively small.

摘要： The present invention relates to a ceramic laminated device including a dielectric ceramic and an Ag electrode. In a dielectric ceramic that can be sintered at low temperatures and has a high dielectric constant and Q value, reactivity between the ceramic and Ag during sintering is suppressed low and segregation of specific elements in the proximity of the electrode is controlled. Thus, a filter having a high Q value and low loss is produced stably. For this purpose, in a ceramic laminated body including at least a ceramic and a Si-containing glass, a ratio of A/B, i.e. a ratio of a Si element concentration (A) within a range at a distance of 5 μm or smaller from the Ag electrode to a Si element concentration (B) within a range at a distance larger than 5 μm from the Ag electrode, is set equal to or smaller than 2.
