Disclosed is a method for using an iron-air assembled cell, wherein, when iron (Fe) contained in a first anode is turned into an iron compound A and, as a result, the voltage of a first iron-air unit cell becomes less than 0.7 V, a second anode is changed to a third anode comprising a third anode active material that contains iron (Fe) as a major component, or a second iron-air unit cell is changed to a third iron-air unit cell which comprises at least a third cathode, the third anode, and a third electrolyte layer present between the third cathode and anode, and which has a voltage of 0.7 V or more and 1 V or less. |

1. A method for using an iron-air assembled cell,
the assembled cell comprising:
a first iron-air unit cell which comprises at least a first cathode, a first anode comprising a first anode active material that contains iron (Fe) as a major component, and a first electrolyte layer present between the first cathode and anode, and which has a voltage of 0.7 V or more and 1 V or less; anda second iron-air unit cell which comprises at least a second cathode, a second anode comprising a second anode active material that contains an iron compound A as a major component, and a second electrolyte layer present between the second cathode and anode, which has a voltage of 0.4 V or more and less than 0.7 V, and which is connected to the first iron-air unit cell in series, wherein, when the iron (Fe) contained in the first anode is turned into an iron compound A and, as a result, the voltage of the first iron-air unit cell becomes less than 0.7 V,
the second anode is changed to a third anode comprising a third anode active material that contains iron (Fe) as a major component, orthe second iron-air unit cell is changed to a third iron-air unit cell which comprises at least a third cathode, the third anode, and a third electrolyte layer present between the third cathode and anode, and which has a voltage of 0.7 V or more and 1 V or less. |
