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

摘要

The invention provides a heat-resistant alloy capable of effectively suppressing diffusion of Cr, as well as an alloy member for a fuel cell, a fuel cell stack device, a fuel cell module and a fuel cell device. A heat-resistant alloy according to the invention includes a Cr-containing alloy, and a Cr-diffusion suppression layer located on at least a part of a surface of the Cr-containing alloy, the Cr-diffusion suppression layer being made by laminating a first layer that contains a Zn-containing oxide and a second layer that does not contain ZnO but contains an (La, Sr)MnO 3 -based perovskite oxide in that order, so that it is possible to effectively suppress diffusion of Cr. By using the heat-resistant alloy for an alloy member for a fuel cell, a fuel cell stack device, a fuel cell module and a fuel cell device each having improved reliability can be obtained.
