Abstract
The electrodeposition of manganese dioxide is obtained by using Pt/C \GDE\ rather than the traditional electrode (Cu) in order to save energy and protect the environment. Thus, the energy-saving mechanism of Pt/C gas diffusion electrode (Pt/C GDE) in high temperature and strong acid MnSO4 media is studied. The cell voltage and the cathode potential of Pt/C \GDE\ and Cu electrode are tested in 30 g/dm3 \H2SO4\ + 120 g /dm3 MnSO4 at 80
