Abstract: An all-solid-state battery includes a case, a battery element, and a restraint component. The case accommodates the battery element. The battery element includes an electrode part and a resin part. The resin part covers at least a part of a side face of the electrode part. The restraint component applies a first pressure to the electrode part. The restraint component applies a second pressure to the resin part. The ratio of the second pressure to the first pressure is from 1.5 to 18.

Abstract: An apparatus for purifying exhaust gas exhausted from an internal combustion engine, using two or more honeycomb structure-type catalysts (X) and (Y). The catalyst (X) contains the support material of the zirconium oxide as a main component which loads a Rh component on the support material of zirconium oxide and substantially does not contain a cerium component, and a cerium-containing oxide which substantially does not load the Rh component, and the catalyst (X) does not substantially contain Pt component and Pd component. The catalyst (Y) contains the support material of the cerium-zirconium composite oxide as a main component which loads a Rh component on the support material of cerium-zirconium composite oxide and which contains cerium of 1 to 20% by weight, in an oxide equivalent, and zirconium of 99 to 80% by weight, in an oxide equivalent, and the catalyst (Y) does not substantially contain Pt component and Pd component.

Abstract: A platinum alloy electrocatalyst, composed of a platinum-copper alloy containing 15 to 50 atomic percent of copper (the balance being platinum) and supported on a suitable carrier, shows high activity over long periods because of the enhanced specific activity of supported metal and improved maintainability of its specific surface area. Thus acid-electrolyte fuel cells using the electrode comprising such an electrocatalyst feature better output performances and longer service life than fuel cells using conventional electrodes.
