Title:
PEROVSKITE-TYPE COMPOSITE OXIDE POWDER
Document Type and Number:
WIPO Patent Application WO/2022/013903
Kind Code:
A1
Abstract:
The perovskite-type composite oxide powder is represented by the general formula ABO3-δ (where δ represents oxygen deficiency, and 0 ≤ δ < 1), an element contained at A site being LA, elements contained at B site being Co and Ni, and the crystallite diameter obtained by the Williamson-Hall method being 20-100 nm inclusive. When used as an air pole material of a fuel cell, an air pole that has a low resistance and a high electroconductivity is thereby obtained.
