Definitions

  • This disclosure relates to electrochemical cells, electrochemical cell devices, modules, and module housing devices.
  • a fuel cell is a type of electrochemical cell that can generate electricity using a fuel gas such as a hydrogen-containing gas and an oxygen-containing gas such as air.
  • the electrochemical cell includes a metal plate, an element portion, and an intermediate layer.
  • the metal plate has a first surface and a second surface located opposite the first surface.
  • the element portion has a first electrode facing the first surface, a solid electrolyte layer, and a second electrode located opposite the first electrode across the solid electrolyte layer.
  • the intermediate layer is located between the first surface and the first electrode. When viewed in a plan view from the second electrode side, at least a portion of the contour of the intermediate layer is located outside the contour of the element portion.
  • the electrochemical cell device disclosed herein also has a cell stack including the electrochemical cell described above.
