摘要: The present invention relates to a catalyst for solid polymer fuel cells in which catalyst particles including platinum and a transition metal M are supported on a carbon powder carrier. The catalyst of the present invention is a catalyst for solid polymer fuel cells in which a molar ratio (Pt/M) of platinum to the transition metal M that form catalyst particles is 2.5 or more, and a ratio (SCOMSA/SBET) of a platinum specific surface area (SCOMSA) measured by a CO adsorption method to a catalyst specific surface area (SBET) measured by a BET method is 0.26 or more and 0.32 or less. The catalyst can be produced by preparing an alloy catalyst, then washing the alloy catalyst with a platinum compound solution, and additionally supplying platinum to the surfaces of catalyst particles.

摘要: A sealing structure with a surface of a base material with a through-hole, an underlying metal film, and a sealing member bonded to the underlying metal film to seal the through-hole. The sealing member includes a compressed product of a metal powder including gold having a purity of 99.9% by mass or more and a lid-like metal film including a bulk-like metal including gold and having a thickness of not less than 0.01 μm and not more than 5 μm. The sealing material includes an outer periphery-side densified region in contact with an underlying metal film and a center-side porous region in contact with the through-hole. The shape of pores in the densified region is specified, and the horizontal length (l) of a pore in the radial direction at any cross-section of the densified region and the width (W) of the densified region satisfy the relationship of l≤0.1W.

摘要: An electrode structure of a back electrode including metal layers laminated in the following order: a Ti layer, a Ni layer, and a Ag alloy layer. The Ag alloy layer includes an Ag alloy and an addition metal M selected from Sn, Sb, and Pd. The electrode structure is configured such that when subjected to elemental analysis with an X-ray photoelectron spectrometer in the depth direction from the Ag alloy layer to the Ni layer, on the boundary between the Ni layer and the Ag alloy layer, an intermediate region where spectra derived from all the metals, Ni, Ag, and the addition element M, can be detected is observable, and, when each metal content in the intermediate region is converted based on the spectra derived from all the metals Ni, Ag, and the addition element M, the maximum of the addition element M content is 5 at % or more.
