New active electrodes have been developed for electrochemical devices (fuel cells and electrolyzers for production of pure hydrogen and oxygen): Oxygen electrodes based on manganite and ferrite-cobaltite, Fuel electrodes based on nickel cermet.

The work was done in collaboration with IEP UB RAS.

        ADVANTAGES:

• High electrochemical activity.

• Effcient operation at 500^ОС and higher.

• High specifc characteristics.

• Operation at a high current density (up to 1 А/cm²) at anovervoltage of up to 100 mV.

• The confrmed service life is over 2000 hours.

• A considerable reduction in power consumption and better effciency of power installations.

• Universality, the use with traditional electrolytes based on zirconia and electrolytes of the new generation based on ceria or lanthanum gallate.
