摘要
Abstract
Oxygen electrode is a dominant electrode of SPE water electrolyzer (WE), of which diffusion layer and catalyst have direct influence on the performance of WE. The titanium oxygen electrode diffusion layers obtained by thermal decomposition, acid immersion, electro-deposition surface modification were evaluated. The effects of oxygen electrode catalyst, temperature, and oxygen electrode diffusion layer on the performance of WE were also discussed. The results showed that the resistance of Ti oxygen electrode diffusion layer decreased after electro-deposition treatment, and did not increase even if it was exposed to the atmosphere for a long time. IrO2-RuO_2 oxygen electrode catalyst has the best catalytic characteristic. Electrolysis voltage decreased increasing temperature. The WE performance was obviously enhanced when electro-deposited Ti mesh was used as oxygen electrode diffusion layer, its current density was more than 1 A/cm~2 at atmosphere pressure,70 ℃, 1.65 V.关键词
