摘要: The understanding and development of functioning systems are crucial steps for microbial fuel cell (MFC) technology advancement. In this study, a compact spiral wound MFC (swMFC) was developed hydraulic residence time distribution (RTD) tests were conducted to investigate the flow characteristics in systems. Results show that two-chamber swMFCs have high surface area volume ratios 350–700 m 2 /m 3 , by using oxygen cathode without metal-catalysts, maximum power densities 42 W/m based on total 170 effective volume. step-input tracer study identified 20–67% anodic dead space, which presents new opportunities system improvement. Electrochemical tools revealed very low ohmic resistance but charge transfer diffusion due catalyst-free reduction. configuration combined with RTD tool offers holistic approach optimization.
