Abstract
The thermal stability and thermal degradation kinetics of proton-exchange membrane were investigated, as the membrane reacted with Fenton reagent at 80°C. Non-isothermal kinetic data of the membrane were analyzed by using the thermo-gravimetry analysis and the Kissinger、Flynn-Wall-Ozawa and Friedman methods under the conditions of flowing gas nitrogen and the heating rate of 5、10 and 20°C/min. The minimum temperature of the thermal degradation is greater than 360.8°C in the conversion rate of 10%. The thermal decomposition process occurred one step. The average value of apparent activation energy is 245.48kJ/mol, pre-exponential factor is 2.52×1018 min-1, the reaction mechanism is controlled by D4.
