Hydrogen energy and fuel cell technology

Hydrogen:
Hydrogen is an energy carrier, not an energy source, and can transport or store large amounts of energy. Hydrogen can be used in fuel cells to generate electricity, generate electricity or provide heat.

Hydrogen is a clean secondary energy carrier, which can be easily converted into electricity and heat with high conversion efficiency and has various sources. Using renewable energy to achieve large-scale hydrogen production, through the bridging effect of hydrogen, it can not only provide hydrogen source for fuel cells, but also can be converted into liquid fuel in a green way, so that it is possible to realize a sustainable cycle of smooth transition from fossil energy to renewable energy. , spawning a sustainable hydrogen economy. As a bridge connecting renewable energy and traditional fossil energy, hydrogen energy can play a bridging role in realizing the “hydrogen economy” and the current or “post-fossil energy era” energy system. Therefore, the utilization of hydrogen energy as a clean energy is an important part of the future energy transformation.

The fuel cell:
Fuel cells combine hydrogen and oxygen to generate electricity, heat and water. Fuel cells are often compared to batteries. Both convert the energy produced by chemical reactions into usable electricity. However, as long as fuel (hydrogen) is supplied, the fuel cell will generate electricity without losing charge.
Fuel cells are a promising technology that can be used as a source of heat and electricity for buildings, as well as as a power source for electric motors that propel vehicles. Fuel cells work best on pure hydrogen. But fuels like natural gas, methanol and even gasoline can be reformed to produce the hydrogen needed for fuel cells. Some fuel cells can even use methanol directly as fuel without the need for a reformer.
fuel cell technology. Hydrogen fuel cells can efficiently and cleanly convert chemical energy directly into electrical energy, which is a more advanced conversion technology than conventional heat engines. The rapid development of fuel cell technology has brought significant opportunities for the transformation of energy power, and fuel cell vehicles are considered to be the main vehicle power source in the post-fossil energy era. Like electricity, hydrogen, as an energy carrier, can be obtained through the conversion of various primary energy sources, becoming a bridge for the conversion of fossil energy to non-fossil energy and from low carbon emissions to zero carbon emissions.

The hydrogen energy industry chain mainly includes:
Hydrogen production, storage, transportation and application. Hydrogen can be widely used in traditional fields as well as emerging hydrogen energy vehicles (including passenger cars, commercial vehicles, logistics vehicles, forklifts, rail cars, etc.) and hydrogen energy power generation (including combined heat and power distributed generation, power generation, etc.) energy storage, backup power, etc.).

Hydrogen energy development focus:
Common key technologies such as fuel cell stacks, basic materials, control technology, and hydrogen storage technology; key components; infrastructure construction such as hydrogen, hydrogen transportation, and hydrogenation.
