The correct way to put it is that the anode generates O2 and the cathode generates H2. Electrons exit the cathode (negative electrode) and enter through the anode. H2SO4 is often added to the electrolysis of H2O. Here, the essence of H2O is that H+ (provided by sulfuric acid) loses electrons and becomes H2, and OH- (from the ionization of H2O) gains electrons and becomes O2. In summary, H2 is generated at the cathode and O2 is generated at the anode. The role of H2SO4 is obviously adapted to improve the conductivity of the solution and facilitate electrolysis.
It's entirely possible
1 If you have a power grid there, you can choose to connect it to the grid to produce electricity. If you don't use batteries, this is the case. designed to be 250 kW, which can be essentially self-sufficient during the day, or a small amount of power is drawn from the grid, so the whole system includes: solar panels,s inverters, mounting brackets (we choose the fixed type at low latitudes, and you can choose the two-axis tracking type at high latitudes, which is slightly more expensive), cables and supporting devices, confluence and protection. The total cost of installation, labor and other expenses is less than 2 million. While the labor cost in Qinghai is slightly higher than the mainland, it is still around 200 W. The main cost is the solar panels, followed by the inverter and mounting brackets. These three elements represent more than 85% of the total. cost. If you use electricity at night, you must draw electricity from the city grid.
2. If you can follow the relevant procedures and get support from relevant policies, you can design a 500 kW power generation system without batteries. Unused energy generated during the day can be transconnection to the electricity network. , which is equivalent to selling electricity during the day, then buying back the electricity sold during the day for use at night. The total system price is the same as above: 1 total system price * 2.
