Resumen de: UA129667C2
The invention relates to the energy industry and concerns an iron-iron flow battery system, which implements the process of electrolyte regeneration by introducing into the positive electrolyte circuit of an iron-hydrogen battery powered by hydrogen produced during charging at the negative electrode of an iron-iron flow battery, and Fe3+ ions generated during charging at its positive electrode, and a flow iron-oxygen electrolyzer, which uses the current generated by the flow iron-hydrogen battery to reduce Fe3+ ions in the negative electrolyte and generate hydrogen protons to restore its acidity. As a result, the system reduces the excess Fe3+ released on the positive electrode to Fe2+ in the positive electrolyte, maintains a stable pH value in the negative electrolyte, and reduces the Fe3+ ions in the negative electrolyte that pass from the positive electrolyte through the membrane to Fe2+ ions, thereby reducing corrosion of the negative electrode. The invention ensures elimination of the imbalance in the degree of charge of the positive and negative electrolytes. 28
