Summary: Maintaining electroactive biofilms with good metabolic activity is essential for high and stable performance in bioelectrochemical systems (BESs). Proton transport plays a significant role in biofilm metabolic activity through microenvironment pH, making it crucial to investigate proton transfer properties within the biofilms to enhance BES performance. In this study, the proton transport in electroactive biofilms was explored using in situ microelectrode measurements, which innovatively measured the diffusion coefficient in live biofilms under non-destructive conditions. The non-destructive measurement of diffusion coefficients not only brings the results closer to reality, but also enriches the understanding of biochemical processes and physicochemical information. By combining with a mathematical model, it was demonstrated that the accumulation of protons in the biofilm is a key factor in inhibiting electricity generation. The efficient characterization of proton transfer within the biofilm provides realistic guidance for constructing high-performance BESs.
