Abstract
In an F-type electrochemical cell, in a casing, a positive electrodein which carbon dioxide gas is used as a positive electrode active material and a negative electrodeare placed so as to face each other with a separatortherebetween, and an electrolyte solutionis injected between the positive electrodeand the negative electrode. A tankstoring carbon dioxide gas is connected to the positive electrode, and carbon dioxide gas is supplied to the positive electrodethrough a holding member. 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.
