Abstract :A paper-based membraneless direct hydrogen peroxide fuel cell was developed and tested under different potassium hydroxide concentrations insert ignore into journalissuearticles values(1 to 7 mol lt-1, stepping by 2);, different hydrogen peroxide concentrations insert ignore into journalissuearticles values(1, 2, 3 mol lt-1); and different temperatures insert ignore into journalissuearticles values(20, 30, 40oC);. Moreover, the developed fuel cell was studied for stability under stopped and continuous flow conditions. From the experiments, it was found that the maximum power density of 6.79 mW cm-2 and the maximum open circuit voltage of 0.87 V at 40oC were obtained when the anode solution consisted 2 mol lt-1 H2O2 and 5 mol lt-1 potassium hydroxide and cathode solution consisted 2 mol lt-1 sulfuric acid and 2 mol lt-1 hydrogen peroxide. It was found that if the reactants were supplied constantly into the fuel cell, a current density of 3.12 mA cm-2 was obtained. The developed fuel cell produced energy for 91 minutes when the reactant flow was stopped.
