A kind of production method of air diffusion electrode comprises the following steps:
The deionized water that adds 1000g in container;
Then add 43g NPE mother liquor in this container, use homogenizer high-speed stirred 5 minutes;
After solution fully mixes, add 14g potassium permanganate in this container, high-speed stirred formed mixed liquor in 5 minutes;
Add 58g Vxc-72 type active carbon in mixed liquor, the homogeneous stirring of high speed 10 minutes;
Add again 50g polytetrafluoroethylene mother liquor, stirring at low speed 20 minutes;
Mixed material is changed in drying baker dry, dewater, pulverize the rear dry material that forms, the drying baker temperature is controlled at 120 ℃-140 ℃.
Good effect of the present invention is: 1, solve individual soldier's electrode 10cm
2Area, constant current 600mA discharge, starting voltage is less than the problem of 0.9V.And, can implement continuous voltage greater than 0.9V, 800mA/10cm
2Current density.2, solve mover electrode 210cm2 area, constant current 10A discharge, starting power is less than the problem of 9W.And, can implement continuous voltage greater than 0.9V, 600mA/10cm
2Current density.While 3, solving the electrode constant-current discharge, the problem that power climbs from low to high gradually.
