SUBSTRATE WITH ELECTRODE LAYER FOR METAL-SUPPORTED ELECTROCHEMICAL ELEMENT, ELECTROCHEMICAL ELEMENT, ELECTROCHEMICAL MODULE, SOLID OXIDE FUEL CELL, AND MANUFACTURING METHOD

摘要

Provided is an electrochemical element that has excellent reliability and durability, and is low cost. A substrate with an electrode layer for a metal support type electrochemical element has a metal support, and an electrode layer 2 formed on top of the metal support, and the electrode layer 2 has an area for which the surface roughness (Ra) is 1.0 µm or less.
