DC SOURCE Russian patent published in 2012 - IPC H01M6/04 

FIELD: electricity.

SUBSTANCE: DC source comprises a vessel, a solution of electrolyte in the vessel, two electrodes from heterogeneous materials placed in electrolyte, at the same time electrodes are made of materials with different work functions of an electron from surfaces contacting with electrolyte, and the electrolyte solution contains negative ions, energy of affinity of which is less than work function of the material with lower work function, and positive ions, the first potential of ionisation of which by absolute value is higher than work function of the material with higher work function.

EFFECT: increased reliability and resource of DC sources operation.
