This study evaluates the effect of the current density, pressure, and temperature on the production of hydrogen peroxide, and concentrations over 400 mg L^-1 are reached. The average rate for the formation of hydrogen peroxide is 9.85 mg h^-1, and the effect of increasing electrolyte concentration (3.0 and 30.0 g L^-1 perchloric acid), intensity, and pressure results in values of, respectively, -2.99, -4.49, and +7.73 mg h^-1.
