Solid oxide fuel cell, cell stack device, fuel cell module, and fuel cell device |
摘要 |
A solid oxide fuel cell, a cell stack device, a fuel cell module and a fuel cell device are disclosed. The solid oxide fuel cell includes a solid electrolyte layer, fuel electrode layer and an oxygen electrode layer. The solid electrolyte layer has gas blocking properties and includes first and second main surfaces opposite to each other. The fuel electrode layer is disposed on the first main surface while the oxygen electrode layer is disposed on the second main surface of the solid electrolyte layer. A thickness of the solid electrolyte layer is 40 μm or less. Porosity of the solid electrolyte layer in an arbitrary cross section thereof is 3 to 15% by area. An average pore diameter of pores in the solid electrolyte layer is 2 μm or less. |

1. A solid oxide fuel cell, comprising:
a solid electrolyte layer that has gas blocking properties, the solid electrolyte layer comprising first and second main surfaces opposite to each other; a fuel electrode layer on the first main surface; and an oxygen electrode layer on the second main surface; wherein the solid electrolyte layer is a single layer; a thickness of the solid electrolyte layer is 40 μm or less; a porosity of the solid electrolyte layer in an arbitrary cross section of the solid electrolyte layer is 3 to 15% by area; and an average pore diameter of pores in the solid electrolyte layer is 2 μm or less. |
