On the other hand, oxygen in the air diffuses through the air electrodes 3 and 5, takes in electrons from an external circuit at the air electrode 5, becomes oxygen ions, diffuses through the solid electrolyte membrane 2, and connects the polygonal columnar fuel electrode 1 to the solid electrolyte membrane. At the interface with 2, it reacts with the hydrogen and carbon monoxide to generate water vapor and carbon dioxide, and also releases electrons to the external circuit. Therefore, an electromotive force is generated in the external circuit with the air electrodes 5 and 3 as positive electrodes and the polygonal columnar fuel electrode 1 as a negative electrode, and the battery functions as a battery.
