Substrate with Electrode Layer for Metal-Supported Electrochemical Element, Electrochemical Element, Electrochemical Module, Solid Oxide Fuel Cell and Manufacturing Method

摘要

Provided is a low-cost electrochemical element that has excellent reliability and durability. A substrate with an electrode layer for a metal-supported electrochemical element includes a metal support and an electrode layer formed on/over the metal support, and the electrode layer has a region with a surface roughness of 1.0 μm or less.
