Principle of Hydrogen Fuel Power Cell

Hydrogen energy fuel power battery is pollution-free to the environment. It uses electrochemical reaction instead of burning or energy storage battery. The most typical traditional backup power method, combustion will release pollutants such as COx, NOx, SOx gas and dust. . Fuel power batteries will only show water and heat. If hydrogen is produced through renewable energy, the entire cycle is a process without the emission of harmful substances. (Schematic diagram of the principle of hydrogen fuel power cell) Hydrogen fuel power cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water, which supplies hydrogen and oxygen to the anode and cathode respectively. After hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to the cathode through an external load. The basic principle of the hydrogen energy fuel power cell is the reverse reaction of the electrolysis of water. Hydrogen and oxygen are supplied to the anode and the cathode respectively. After the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to the cathode through an external load. Strictly speaking, a hydrogen fuel cell is a power generation 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 the hydrogen fuel power battery are made of special porous materials, which is a key technology of the hydrogen fuel power battery. It not only has to provide a large contact surface for the gas and the electrolyte, but also affects the chemical reaction of the battery. Catalytic use. Hydrogen has many advantages as an energy source. Hydrogen can be produced by photolysis of water, which has a large reserve and relatively low cost; after the combustion of hydrogen fuel, water is generated, which is a harmless and clean energy source for combustion. Hydrogen loses less than electricity in storage and transmission, and has a high calorific value of hydrogen combustion. The heat generated by the combustion of 1 kilogram of hydrogen is equivalent to the calorific value of 3 kilograms of gasoline or 4.5 kilograms of coke. However, in application, the storage and transportation of hydrogen and the use of solar energy to split water to produce hydrogen have always been the bottleneck restricting the development of hydrogen energy. The basic principle of the hydrogen fuel power cell is the reverse reaction of the electrolysis of water. Hydrogen and oxygen are supplied to the anode and the cathode respectively. The hydrogen diffuses out through the anode and reacts with the electrolyte. The released electrons reach the cathode through an external load. A power generation device that directly converts the chemical energy in the fuel and oxidizer into electrical energy. From the outside, there are positive and negative electrodes and electrolytes, etc., like a battery, but in fact, the hydrogen fuel-powered battery vehicle does not need to be charged, only hydrogen is added. For example, the battery of a pure electric vehicle is like a power storage station, and a hydrogen fuel-powered battery is like a power station.
