Effect of COD and H2O2 concentration on DC-MFC

has been made to use hydrogen peroxide (H2O2) in different concentrations as substitute for ferricyanide and permanganate as catholyte in DC-MFCs. It has been found that the power generation was not significantly affected by the 20%-60% and 100% concentrations while 80% concentration exhibited higher power generation. Power densities were virtually dependent on the chemical oxygen demands (CODs) as observed to be 24.56 W/m2 for Balance substrate (7562 mg/L) against 80% H2O2. This confirms that H2O2 is a very powerful oxidizing agent between the concentrations of 70%-90%.
