Solid oxide cell and solid oxide cell stack

Abstract

A solid oxide cell includes a hydrogen electrode, a solid oxide electrolyte layer, and an oxygen electrode. The hydrogen electrode includes: a first hydrogen electrode layer having a first surface and a second surface, the first surface being in contact with the oxide electrolyte layer, the second surface being opposite to the first surface; and a second hydrogen electrode layer in contact with the second surface. The first hydrogen electrode layer has a first metal particle and a first metal oxide particle. The second hydrogen electrode layer has a second metal oxide particle with a second metal particle supported with the second metal oxide particle.
