Abstract
(EN)
 Provided is a solid electrolyte laminate equipped with: a solid electrolyte layer having proton conductivity; and a cathode electrode layer comprising a lanthanum strontium cobalt composite oxide (LSC), and laminated on one side of the electrolyte layer. Also provided is a manufacturing method for the solid electrolyte laminate. The solid electrolyte laminate can further be equipped with an anode electrode layer comprising nickel-yttrium doped barium zirconate (Ni-BZY). The solid electrolyte laminate is suitable for a fuel cell that operates in an intermediate temperature region not exceeding 600°C.
