The performance of the solid polymer electrolyte(SPE) membrane electrode composite ozone generator has been examined in deionized water for more than 10000 hours with the current density 1.5 Acm ̄(-2).The average current efficiency of O_3 evolution is about 20%.The optimal specific power consumption is 58.3 Whg ̄(-1)(O_3).The stability of the anode catalysts on SPE membrane composite ozone generator has been studied by X-ray diffraction and atomic absorption spectrometry techniques.The results show that both the current efficiency of O_3 production and the stability of the composite with β-PbO_2 anode catalyst are better than those with the mixed α-PbO_2 and β-PbO_2 catalyst.
