Hydrogen energy fuel cells

Hydrogen energy fuel cell——Fuel cell coating——Ultrasonic spraying——Shanghai Yangmi ultrasonic spraying

Fuel cell is a kind of energy conversion device, it is based on the electrochemical principle, that is, the operating principle of galvanic cell, isothermal stored in fuel oxidized chemical energy is directly converted into electrical energy, so the actual process is REDOX reaction. The fuel cell is mainly composed of anode, cathode, electrolyte and external circuit. Fuel gas and oxide gas are transported through the anode and cathode of the fuel cell, respectively. The fuel gas emits electrons at the anode, which travel through an external circuit to the cathode and combine with the oxide gas to form ions. Under the action of an electric field, ions migrate through the electrolyte to the anode, where they react with the fuel gas to form a loop and generate an electric current.

Fuel cells also generate a certain amount of heat due to their own electrochemical reactions and the internal resistance of the cell. In addition to conducting electricity, the positive and negative electrodes of the battery act as catalysts for REDOX reactions. When the fuel is hydrocarbon, the anode requires higher catalytic activity. The anode and cathode are usually porous to facilitate the passage of reaction gases and the expulsion of products. Electrolytes can transfer ions and separate fuel and oxidation gases. The electrolyte is usually a dense structure to prevent the mixing of two gases in the cell from causing a short circuit.

The reliability of fuel cell refers to the ability of fuel cell engine to complete the specified function under the specified conditions and within the specified time, which mainly reflects the characteristics of continuous stable and correct operation of fuel cell engine. The reliability of fuel cell engine determines the reliability of fuel cell vehicle to a large extent. The life of proton exchange membrane fuel can reach as high as 100000h in stable operation. The durability of fuel cell vehicle is mainly affected by the performance decline and life limit of fuel cell.
