Both archaea are able to grow at high salt concentrations. By increasing the media conductivity, the internal resistance was diminished, improving the MFC's performance. Without any added redox mediator, maximum power (P max) and current at P max were 11.87/4.57/0.12μWcm−2 and 49.67/22.03/0.59μAcm−2 for H. volcanii, N. magadii and E. coli, respectively. When neutral red was used as the redox mediator, P max was 50.98 and 5.39μWcm−2 for H. volcanii and N. magadii, respectively. In this paper, an archaea MFC is described and compared with other MFC systems; the high salt concentration assayed here, comparable with that used in Pt-catalyzed alkaline hydrogen fuel cells, will open new options when MFC scaling up is the objective necessary for practical applications.
