Explain Hydrogen Fuel Cell
Hydrogen, a colorless and odorless gas, is lighter than air, and its chemical symbol is H. Today there are hydrogen fuel cells, which are exquisite energy conversion devices.
The principle of its operation is based on electrochemical reactions. Using hydrogen as fuel and oxygen as oxidant, inside the battery, hydrogen atoms are decomposed into protons and electrons. The protons move to the cathode through the electrolyte membrane, and the electrons flow along the external circuit to form an electric current that can be powered by various devices. At the cathode, protons and electrons combine with oxygen to form water, which is the product of the reaction and is clean and non-staining.
The advantages of hydrogen fuel cells are significant. First, high efficiency, compared with traditional fuel engines, the energy conversion rate is quite high, which can effectively utilize energy. Second, it is clean and environmentally friendly, the reaction is only raw water, and there is no harmful exhaust emissions, which is of great benefit to environmental protection. Third, it is quiet and silent, and there is not much noise during operation, which can create a quiet environment.
However, it also faces some challenges. Hydrogen production, storage and transportation are not easy. Production requires energy, storage requires high pressure or low temperature conditions, and transportation also requires special equipment, which is quite expensive.
However, with time and technology improving day by day, hydrogen fuel cells are expected to shine in transportation, power generation and other fields, opening up a new path for human energy future.
