This open access publication is about investigations of different modes of operation and different materials with and without recombination cell to avoid charge carrier loss and thus to increase cycle stability. We have also investigated regeneration of the electrolyte with external hydrogen and successfully restored lost capacity. Iron/iron redox flow batteries thus form an interesting possibility with an exceptionally inexpensive and safe energy storage material.
