Power generator

A power generator, comprising:

• a fuel electrode that receives a supply of fuel gas;
• an air electrode that receives a supply of air;
• an electrolyte layer disposed in between the fuel electrode and the air electrode;
• a gas flow channel that circulates therein the fuel gas or the air, with the fuel electrode or the air electrode being exposed to at least part of the gas flow channel;
• a porous body filled in the gas flow channel;
• and
• a porous sheet in contact with the porous body and the fuel electrode or the air electrode, the porous sheet being made of a material having electrical conductivity, the material having pores formed to spread in a uniform manner, the pores being larger in diameter than pores formed in the porous body;
• wherein a surface of the porous body is covered with the porous sheet so as to form an electrically conductive path by completely enclosing a cross-sectional area of the gas flow channel.
