Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The traditional chamber‐based microbial fuel cell (MFC) often has the disadvantages of high ohmic resistance, large volume requirements, and delayed start‐up. In this study, paper‐shaped MFCs utilizing a porous carbon anode, a solid Ag₂O‐coated carbon cathode, and a micrometer‐thin porous polyvinylidene fluoride (PVDF) separator are investigated to address the classical MFC issues. The Ag₂O‐coated cathode has a low overpotential of 0.06 V at a reducing current of 1 mA compared to a Pt–air cathode. Rapid inoculation by filtration results in an instantaneous power density of 92 mW m⁻² with an internal resistance of 162 Ω. Integrated current over the first 30 min of operation has a linear relation with microbial concentration.</p> </abstract>
