摘要：

The membrane electrode assembly was prepared by a catalyst coated membrane (CCM) with an effective active area of 10 x 10 cm(2) in this work. Porous titanium plates with different diameters were used as anode collectors to study the polarization curve and electrochemical impedance spectroscopy (EIS) of the electrolyzer. The results show that the pore size of a porous titanium plate on the anode side has a significant effect on the performance of the electrolyzer. The best cell performance was obtained when the median diameter of the anode titanium plate was 12.3 um. When the current density is 1 A/cm(2), the battery voltage is 2.253 V.
