Abstract
In an F-type electrochemical cell 20, in a casing 21, a positive electrode 23 in which carbon dioxide gas is used as a positive electrode active material and a negative electrode 25 are placed so as to face each other with a separator 27 therebetween, and an electrolyte solution 28 is injected between the positive electrode 23 and the negative electrode 25. A tank 30 storing carbon dioxide gas is connected to the positive electrode 23, and carbon dioxide gas is supplied to the positive electrode 23 through a holding member 29. By supplying carbon dioxide gas to the positive electrode in such a manner, the cell can be operated as a battery. Furthermore, when used a primary battery, carbon dioxide can be immobilized in the battery, which is desirable.
