Corrigendum to “Gauging sediment microbial fuel cells using open-circuit auxiliary electrodes” [J. Power Sources 527 (15 April 2022) 231216] (Journal of Power Sources (2022) 527, (S037877532200235X), (10.1016/j.jpowsour.2022.231216))

To the attention of the Journal of Power Sources editor and readers: The authors would like to highlight the fact that auxiliary electrodes were previously proposed in research articles by Ieropoulos et al. (2018) and Iwona et al. (2021), who were not appropriately cited in the original version of this manuscript. A patent has also been registered by Ieropoulos et al. (2020). In their work, the auxiliary electrodes are referred to as isolated electrodes included on each microbial fuel cell (MFC) half-cell. Their work described current switching mechanisms to attain MFC modulation (Ieropoulus et al., 2018) and highlighted the possible uses in electrosynthesis (Gajda et al., 2021). We believe our work is relevant and complementary with their findings since we extended the scope of auxiliary electrodes to sediment and benthic MFCs. Additionally, we designed a novel electrode configuration with integrated auxiliary electrodes, which represents a technological advance. We believe the open circuit auxiliary electrode or isolated electrodes are an important addition to any microbial electrochemical technology (MET) configuration.
