て燃お１電池発電システムを構成している。(Prior Art) Fuel cells are conventionally known as devices that directly convert energy contained in fuel into electrical energy. Generally speaking, this type of fuel cell has a pair of porous power collectors arranged as a fuel electrode and an oxidizer electrode with an electrolyte layer in between, and a fuel such as hydrogen is placed on the back side of the fuel electrode, and a fuel such as hydrogen is placed on the back side of the oxidizer electrode. This method utilizes the electrochemical reaction that occurs when an oxidizing gas such as air is brought into contact with the device. In addition, in this type of fuel cell, in order to absorb the heat generated by the electrochemical reaction, multiple cooling pipes are installed inside the fuel cell main body, and cooling water is circulated and supplied to the cooling pipes. This constitutes a single-cell combustion power generation system.
