Welcome to Website of Shanghai Pearl Hydrogen Energy Technology Co.
Fuel cell is a kind of chemical device, which directly converts the chemical ability of fuel into electrical energy, also known as electrochemical generator. Fuel cell is a new energy-saving and environment-friendly power generation technology, which will grow rapidly under the background of "carbon neutralization"! It is the fourth generation technology after hydraulic power generation, thermal power generation and atomic power generation. Because the fuel cell converts the Gibbs free energy of the fuel into electric energy by electrochemical reaction, it is not limited by the Carnot cycle effect, so it has high efficiency; In addition, fuel cell fuel and oxygen as raw materials, no mechanical transmission parts, no noise pollution, very little exhausted gas. It can be seen that from the perspective of energy conservation and ecological environment protection, fuel cell is the most developed power generation technology.
Fuel cell has high power, high power and high proportion of energy, high economy. Fuel cell, originated in the 19th century, is a kind of power generation device, which directly converts fuel into electrochemical reaction through electrochemical reaction. In the 1970s-1980s, the global energy crisis and aerospace competition greatly promoted the development of fuel cells. Since the 1990s, people have paid more and more attention to environmental protection. Fuel cells are reliable and easy to operate. The harmful products of electrochemical reaction are very small. As a result, the core technology continues to go bankrupt and is widely used in business, and it is also one of the most developed energy and power units.
Principle of fuel cell power generation
Hydrogen fuel cell is a clean cell which uses chemical element hydrogen as fuel. The principle of hydrogen production is that hydrogen is injected into the anode (i.e. negative electrode) of fuel cell, catalyst such as platinum acts, and electrolyte reacts to the electrode to lose electrons, and hydrogen ions pass through proton exchange membrane. It reaches the cathode of the fuel cell (that is, the positive electrode), and the electrons reach the positive electrode of the fuel cell through the external circuit to generate current.
The fuel cell composition mainly consists of two parts: membrane electrode assembly (MEA) and bipolar plate. Other structural components include seal, end plate and collector. Stacks are structures, piles and monitoring units (CVM), external packages and fluid manifold assemblies, and fuel cell modules.
The company has 30 Chinese patents and 2 international patents; Breakthrough progress has been made in the development, production and application of medium and small power fuel cell system. Focus on the core business of communication fuel cell backup power supply, UAV power system, vehicle fuel cell and teaching aid products.
