Abstract
Key findings
- Uncompensated resistance significantly affects bioelectrochemical system performance, leading to inaccurate measurements and conclusions.
- Double layer capacitance and junction potential also impact system performance, but to a lesser extent than uncompensated resistance.
- A new method is proposed to account for these effects and improve system characterization.
