Metal Support for Electrochemical Element, Electrochemical Element, Electrochemical Module, Electrochemical Device, Energy System, Solid Oxide Fuel Cell, Solid Oxide Electrolytic Cell, and Method for Manufacturing Metal Support

摘要

A metal support for an electrochemical element has a plate shape as a whole, and is provided with a plurality of penetration spaces that pass through the metal support from a front face to a back face. The front face is a face to be provided with an electrode layer. Each of front-side openings that are openings of the penetration spaces formed in the front face has an area of 3.0×10⁻⁴ mm² or more and 3.0×10⁻³ mm² or less.
