Özet
A paper-based membraneless direct hydrogen peroxide fuel cell was developed and tested under different potassium hydroxide concentrations (1 to 7 mol lt-1, stepping by 2), different hydrogen peroxide concentrations (1, 2, 3 mol lt-1) and different temperatures (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.
