Fuel cell and hydrogen technologies (FCH)


        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 or provide heat.

        Hydrogen is a clean secondary energy carrier that can be easily converted into electricity and heat, has a high conversion efficiency, and has multiple sources. Using renewable energy to achieve large-scale hydrogen production, through the bridging effect of hydrogen, it can not only provide a hydrogen source for fuel cells, but also can be green converted into liquid fuels, so that it is possible to achieve a sustainable cycle of smooth transition from fossil energy to renewable energy , To give birth to a sustainable hydrogen economy. As a bridge connecting renewable energy and traditional fossil energy, hydrogen energy can bridge the realization of the "hydrogen economy" and the current or "post-fossil energy era" energy system. Therefore, the use of hydrogen energy as a clean energy source is an important part of the future energy transformation.

The fuel cell:

       Fuel cells combine hydrogen and oxygen to produce electricity, heat and water. It is common to compare fuel cells with batteries. Both convert the energy produced by chemical reactions into usable electrical energy. However, as long as fuel (hydrogen) is provided, the fuel cell will generate electricity without losing its charge.

       Fuel cells are a promising technology that can be used as a heat source and electricity for buildings, and as a power source for electric motors that propel vehicles. Fuel cells work best on pure hydrogen. But fuels such as natural gas, methanol and even gasoline can be reformed to produce hydrogen for fuel cells. Some fuel cells can even use methanol directly as fuel without using 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 a major opportunity for the transformation of energy and power, and fuel cell vehicles are considered to be the main vehicle power source in the post-fossil energy era. Like electric energy, hydrogen, as an energy carrier, can be obtained through the conversion of various primary energy sources, becoming a bridge from fossil energy to non-fossil energy, 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, but also in emerging hydrogen energy vehicles (including passenger cars, commercial vehicles, logistics vehicles, forklifts, rail cars, etc.) and hydrogen power generation (including combined heat and power distributed power generation, power generation Energy storage, backup power supply, etc.).

Development focus of hydrogen energy:

       Common key technologies such as fuel cell stacks, basic materials, control technologies, and hydrogen storage technologies; key components; infrastructure construction such as hydrogen, hydrogen transportation, and hydrogenation.
