摘要：Deteriorated positive electrolyte containing Fe.sup.3 /Fe.sup. 2+ ions for a redoxflow battery is regenerated in a negative electrolyte chamber of an electrolyteregenerating apparatus. For this purpose, a formic acid solution is introduced into apositive electrolyte chamber of the electrolyte regenerating apparatus and a voltage isapplied between a negative electrode of the negative electrolyte chamber and a positiveelectrode of the positive electrolyte chamber, whereby excessive Fe.sup.3+ ions in thedeteriorated positive electrolyte are changed to Fe.sup.2+ ions for regeneration. Theformic acid is changed into carbon dioxide which is not noxious. All gases generated bythe regeneration are not noxious, whereby the regeneration can be carried out withsafety.
