Substrates with electrode layers for metal-supported electrochemical devices, electrochemical devices, electrochemical modules, solid oxide fuel cells, and manufacturing methods

摘要

It is excellent in reliability and durability, and provides an electrochemical element of low cost. The substrate with an electrode layer for a metal-supported electrochemical device has a metal support and an electrode layer 2 formed on the metal support, and the electrode layer 2 has a region having a surface roughness Ra of 1.0 µm or less.
