1. The basic principle of a hydrogen fuel cell is the reverse reaction of water electrolysis. Hydrogen and oxygen are supplied to the anode and cathode, respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are sent to the anode and cathode, respectively. released and reach the cathode via an external charge.
2 Hydrogen fuel cells do not pollute the environment. They use electrochemical reactions instead of combustion (petrol, diesel) or energy storage (battery). The most common traditional backup power solution is the combustion of such pollutants. because COx, NOx, SOx and dust will be released. Fuel cells only produce water and heat. If the hydrogen is produced via renewable energy, the entire cycle is completely emissions-free.
3. Strictly speakinger, a hydrogen fuel cell is an electricity production device. Like a power plant, it is an electrochemical power generation device that directly converts chemical energy into electrical energy. In addition, the electrodes of hydrogen fuel cells are made of special porous materials, which is a key technology of hydrogen fuel cells. It not only provides a large contact surface for gas and electrolyte, but also catalyzes the chemical reaction of the battery. The fuel cell operates quietly, with only about 55 dB of noise, which is equivalent to the level of a normal conversation. This makes the fuel cell suitable for indoor installation or where there are exterior noise restrictions.
