Title:
COMPOSITE BODY, COLLECTOR MEMBER, FUEL BATTERY CELL DEVICE, AND FUEL BATTERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/077445
Kind Code:
A1
Abstract:
[Problem] To provide a composite body, a collector member, a fuel battery cell device, and a fuel battery device in which Cr diffusion can be sufficiently reduced and in which electroconductivity is excellent. [Solution] This invention is provided with a substrate (200) containing Cr, and a coating layer (205) for covering at least a part of the substrate (200). The coating layer (205) is provided with: a first layer (201) including Cr from among constituent elements other than oxygen and having a chromium oxide crystal; a second layer (202) disposed on the first layer (201), the second layer including Zn, Al, and Cr from among constituent elements other than oxygen and having a spinel-type crystal; a third layer (203) disposed on the second layer (202), the third layer including Zn and Mn from among constituent elements other than oxygen and having a spinel-type crystal; and a fourth layer (204) disposed on the third layer (203), the fourth layer including Zn from among constituent elements other than oxygen and having a zinc oxide crystal.
