I am working on dual chambered microbial fuel cell. I have been trying to plot polarisation and power density curve for my system using linear sweep voltammetry. however, for some unclear reason i am getting an upside down power density curve. I am using Autolab poteniostat with nova 2.1.3 software. I am using anode as working electrode, cathode as counter electrode and Ag/AgCl electrode as reference electrode in anodic chamber. Please suggest a correct way (steps and connections) of plotting power density curve using linear sweep voltammetry.
P.S. I am also attaching the picture of the LSV obtained by me and the one reported in literature.
