A high-temperature solid-state oxide fuel cell capable of storing energy

The invention provides a high-temperature solid-state oxide fuel cell capable of storing energy. The structure of the battery is designed to be a hollow structure of an upper and lower symmetrical flat plate supported by an anode. The material of the anode support layer comprises NiO. In the working process, first H2 is introduced to enable H2 to reduce NiO to generate simple substance Ni, at thesame time, H2 is oxidized into water vapor H2O to be stored in the battery, and then oxidized gas is introduced and the introduction amount of H2 is controlled so that at least part of the simple substance Ni is oxidized to form NiO and is discharged, thereby forming a discharge process; then, during the charging process, NiO is reduced to Ni by electrolysis of water vapor stored in the battery, and H2 is oxidized to water vapor H2O to be stored in the battery. Compared with the prior art, in the charging and discharging process, H2 can be generated ''in situ'' inside the battery and stored, effective energy storage i
