| Abstract: | The characteristic of the unitized regenerative fuel cell and the research actuality of the catalysts used for bifunctional oxygen electrode were reviewed briefly. Three PtIr/C catalysts were prepared by reduction and deposition method. And the catalysts were physically characterized by XRD. The catalysts' electrocatalysis performance was examined in three-electrode system. The results showed that Pt mainly catalyzed the oxygen reduction reaction during fuel cell mode, while Ir mainly catalyzed the oxygen evolution reaction during water electrolysis mode. |
