Electrical characterisation of the M5-21 SSC-MFC unit (a, b) and the M5–11 SSC-MFC unit (c, d). a Polarisation and power curves. The resistive load values ranged from 38,000 to 4 Ω. Each resistor was connected for a period of 10 min. Power normalised by total displacement volume (1.5 L); b Temporal power production under a 2 L 8 h−1 feeding regime. c Polarisation and power curves. The resistive load values ranged from 30,000 to 1 Ω. Each resistor was connected for a period of 10 min. Power normalised by displacement volume (1.7 L). d Temporal power production under two feeding regimes, with an identical daily rate
