1. Hydrogen fuel cell industry
In the hydrogen fuel cell industry chain, the upstream is the preparation, transportation and storage of hydrogen, and the hydrogen fuel cell system is filled with hydrogen at the hydrogen refueling station; the midstream is the production of key components such as electric reactors, and the reactor and accessories are The two parts are integrated to form a hydrogen fuel cell system; at the downstream application level, there are three main directions: transportation, portable power supply and fixed power supply.
Second, the power battery advantages and disadvantages comparison
At present, there are four main technical routes for transportation power sources: lithium ion batteries, hydrogen fuel cells, super capacitors and aluminum air batteries. Lithium-ion batteries, supercapacitors and hydrogen fuel cells are widely used, and aluminum-air batteries are still in the laboratory research stage. For energy replenishment, lithium-ion batteries and supercapacitors are suitable for pure electric vehicles, but require external charging, while hydrogen fuel cell vehicles require external hydrogen filling, and aluminum air batteries require additional aluminum plates and electrolytes.
Comparison of advantages and disadvantages of four technical routes
