The fuel cell membrane reactor to Nafion as the solid electrolyte of the catalytic electrode at different oxygen reduction kinetics of the obtained cathode electrode kinetics of oxygen reduction parameters. Oxygen molecules in the two electron reduction process to obtain hydrogen peroxide , the low current density area , the reaction rate determining step is the first step the electronic exchange ; high current density area , the rate determining step is the oxygen mass transfer, diffusion process . The effects of the electrode structure , electro-catalyst , a cathode alkali concentration and operating conditions such as: temperature , partial pressure of oxygen and an electrolysis voltage of electrocatalytic synthesis result . Steady polarization curve by plotting discussed 25 ~ 60 ℃, 30wt% NaOH solution, oxygen evolution on the anode of nickel process . Changes in comparison electrode kinetic parameters found that: As the temperature increases the oxygen evolution overpotential reduced ; 40 ℃ is the boundary of the electrode process temperatures above this temperature lower activation energy for oxygen evolution . Combined with cathodic oxygen reduction kinetics analysis Electrocatalytic Oxygen Reduction Reaction in Alkaline hydrogen peroxide better experimental conditions , and the results of this analysis for the amplification experiments , from the current efficiency , DC consumption , cell voltage and alkali than other aspects of electrolysis device was evaluated.
