I am facing problems regarding Cycli voltmetery and electrochemical impedence spectroscopy of soil microbial fuel cells. I tried the literature mentioned methods like to put reference electrode into soil near cathode or Counter electrodes act as reference electrodes in Soil MFC or generate anaerobic condition by purging Nitrogen into soil MFC but I did not get curve of CVs and EIS. When I measured the counter as reference electrode I got different width CV curves that match with rare literature review with 1 or 2 research articles. Kindly give the technical solution how I can get peaks in CV and EIS.
What is relation of voltage and current density? either they are inversely proportional to each other with different external resistances? at low current density the voltage should be high or low with different external resistance?kindly guide about its calculation?
Why Graphite electrodes (Anode and cathode) used in microbial fuel cell?
