Hydrogen Compressor

Congratulations: Hydrogen fuel cell air compressor is the first successful one in China! With a market of nearly 100 trillion yuan, blue Ocean electric vehicle cutting-edge technology was born in Xinran !

With the introduction of China's energy conservation and emission reduction, green environmental protection policies, the market demand for efficient, clean energy is increasing. Hydrogen energy, with zero carbon dioxide emissions, no pollution, abundant reserves and recyclable, as well as easy storage, easy transport and other characteristics, is regarded as the ultimate energy in the 21st century. Hydrogen fuel cell is a device that converts the chemical energy of hydrogen and oxygen into electric energy through the reaction of electrodes. The waste discharged is only water and heat. Because there is no carbon emission, hydrogen fuel cell is considered to be the most promising energy at present.

Among them, air compressor plays an important role in hydrogen fuel cell system and is a key component. Different from traditional industrial air compressors, hydrogen fuel cell air compressors require high reliability, long life, oil-free exhaust, low noise, lightweight, miniaturization, low cost, fast response and so on. At present, the hydrogen fuel cell air compressor market is basically monopolized by foreign brands. The domestic research on this kind of air compressor starts late with poor product reliability and unstable performance, and is still in the stage of research and development and small batch trial production. Foreign hydrogen fuel cell air compressor because of early research and development, high reliability, stable performance. However, it is very expensive, with a unit price of more than 100,000 yuan or more than 200,000 yuan, which has become one of the bottlenecks in the development of hydrogen fuel cell industry.  

Xinran automotive hydrogen fuel cell compressor mainly centrifugal type, screw type, Roots type, vortex type and so on.

Centrifugal air compressor has high speed, small size and light weight, but it has surge interval. Under variable working conditions, the performance will become worse, and even affect the service safety and life of the compressor.

Screw type belongs to mechanical supercharging. Under the condition of changing working conditions, its performance is almost unchanged, with high efficiency and high reliability, but the noise is too big and the weight is too heavy.

The pressure value of Roots type cannot reach the optimal efficiency point of hydrogen fuel cell, and the vibration noise is large, and the efficiency is low.

Vortex type is limited by its own structure and occupies a large amount of space. At the same time, the sealing mode of the oil-free scroll compressor is PTFE sealing strip structure. In the process of operation, the sealing strip is worn and its life is short. The reliability is poor when the vehicle is in variable working condition.

Because four types of air compressor have their own advantages and disadvantages, there is no one type of air compressor, can fully meet the requirements of hydrogen fuel cell air compressor for vehicles. At present, the mainstream automotive hydrogen fuel cell air compressor on the market, mainly screw type, Roots type centrifugal.
