Title:
COMPOSITE BODY, COLLECTOR MEMBER, GAS TANK, AND FUEL CELL DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/105578
Kind Code:
A1
Abstract:
Disclosed are: a composite body which is capable of effectively suppressing diffusion of Cr; a collector member; a gas tank; and a fuel cell device. Specifically disclosed is a composite body which comprises: a base (201) that contains Cr; and a first complex oxide layer (203) that is formed on at least a part of the surface of the base (201), contains Zn and Al respectively in the largest amount and in the second largest amount among the constituent elements other than oxygen, and has a spinel crystal structure. Consequently, the composite body is capable of suppressing diffusion of Cr from the base that contains Cr, and has improved long-term reliability. A collector member (20) and a gas tank (34), each of which is formed of the composite body, can have improved long-term reliability. A fuel cell device (30) having excellent long-term reliability can be obtained using the collector member (20) and the gas tank (34).
