When oxygen is supplied as an oxidizing agent to the hollow part of each fuel cell single cell 4, oxygen (N2) and hydrogen (02) are chemically converted into each fuel cell single cell 4 via the ionic conductive solid electrolyte 5. Reacts and produces water (N20
) is generated, and electrons corresponding to the free energy during the reaction are collected on the air electrode 6 side, which is an anode, and the electrons collected on each air electrode 6 are connected to the interconnector 9.
The current is collected from the current through the four-electric fiber felt 10 to the internal current collector tube 2.

。In addition, there are differences in the supply status of high-temperature hydrogen, and
When a temperature difference occurs in the solid oxide fuel cell 1 due to a temperature difference between the hydrogen gas and the side far from the supply side, an electromotive reaction occurs between each fuel cell unit 4 or in a portion of each fuel cell unit 4. Due to this unevenness, the electromotive force of the solid oxide fuel cell 1 as a whole decreases.
