Title:

HEAT-RESISTANT ALLOY, ALLOY MEMBER FOR FUEL CELL, FUEL CELL STACK DEVICE, FUEL CELL MODULE, AND FUEL CELL DEVICE

Document Type and Number:

WIPO Patent Application WO/2010/087298

Kind Code:

A1

Abstract:

Disclosed is a heat-resistant alloy which is capable of effectively suppressing diffusion of Cr. Also disclosed are an alloy member for fuel cells, a fuel cell stack device, a fuel cell module, and a fuel cell device. The heat-resistant alloy comprises a Cr diffusion-suppressing layer wherein a first layer that contains a Zn-containing oxide and a second layer that does not contain ZnO but contains an (La, Sr)MnO3 perovskite oxide are laminated in this order on at least a part of the surface of a Cr-containing alloy, and thus the heat-resistant alloy can effectively suppress diffusion of Cr. By using the heat-resistant alloy for an alloy member for fuel cells, a fuel cell stack device, a fuel cell module and a fuel cell device, each having improved reliability can be obtained.
