Electricity-generation device

An electricity generation device using a fuel cell having a fuel electrode and an air electrode to which a fuel gas and air are supplied, respectively, comprising:

• a fuel gas conduit through which the fuel gas flows;
• a cover configured to cover an outside of the fuel gas conduit and cooperating with a peripheral wall of the fuel gas conduit to form an air passage therebetween, the air passage extending along the fuel gas conduit;
• an air inlet hole formed through the cover to allow air to flow into the air passage;
• and
• an air outlet hole provided downstream of the air electrode exposed to the air passage, to cause the fuel gas conduit and the air passage to communicate with each other, wherein the air outlet hole is configured to create a flow of air in the air passage from a flow of the fuel gas through the fuel gas conduit.
