Table 1

Performance of MFCs based on different cathodic catalysts.

Catalyst	OCV (V)	Internal resistance (Ω)	Maximum power density (mW/m^2)	Maximum current density (A/m^2)	BET (m^2/g)
Without catalyst	0.33	250	32.11	0.22	—
Naturally synthesized MnO2	0.47	200	42.05	0.29	24.91
Hydrothermally synthesized MnO2	0.50	150	119.07	0.49	111.89
