Polttokennojen joustavien grafiittibipolaaristen levyjen maailmanlaajuinen markkinakoko

(Polttokennojen joustavien grafiittibipolaaristen levyjen maailmanlaajuinen markkinakoko)

Grafiitti oli ensimmäinen bipolaarinen levymateriaali, joka kehitettiin. Verrattuna metalli- ja metalliseos bipolaarisiin levyihin, graphite bipolar plates have the advantages of low density, good corrosion resistance, and good affinity with the carbon fiber diffusion layer, which can meet the requirements for long-term stable operation of fuel cells. Kuitenkin, graphite has large porosity, alhainen mekaaninen lujuus, and high brittleness. In order to prevent the working gas from penetrating the bipolar plate and meet the design of mechanical properties, the graphite bipolar plate is usually thicker, resulting in a larger volume and mass of the graphite material. Lisäksi, due to the poor processing performance and low yield of graphite materials, manufacturing costs increase.

 

Flexible graphite bipolar plates are an important part of fuel cells. Their main functions are to provide channels for conducting and transferring reactive gases. Graphite material has good electrical conductivity and chemical stability. Myös, it has a certain degree of flexibility, allowing it to adapt to the deformation and deflection of the fuel cell stack.

According to the latest report of the QYResearch research team, "Global Flexible Graphite Bipolar Plate Market Report for Fuel Cells 2023-2029", the global market size of flexible graphite bipolar plates for fuel cells is expected to reach US$220 million in 2029, with compound annual growth in the next few years. The rate CAGR is 17.3%.

According to a survey by QYResearch's leading enterprise research center, G90's global manufacturers of flexible graphite bipolar plates for fuel cells mainly include Schunk, Ballard Power Systems, Nisshinbo Chemical, jne. 2022, the world's top three manufacturers will hold approximately 51.0% of the market share.

Main drivers

Fuel cells are the largest demand end for graphite bipolar plates. Benefiting from national policy support and the improvement of national living standards, my country's demand for new energy vehicle purchases is increasingly strong. As a power component of new energy vehicles, the development of fuel cells is accelerating.

 

Main hindrance factors

Graphite bipolar plates are the earliest to achieve commercial application but have disadvantages such as large thickness and low mechanical strength. Viime vuosina, tekniikan kehityksen myötä, metal bipolar plates, as an emerging product of bipolar plates, have seen increasing industry prosperity. Metal bipolar plates have the advantages of low production cost, kevyt, and high mechanical strength. As lightweight automobiles accelerate, metal bipolar plates, as bipolar plates for high-end fuel cells, have continued to increase their market share, reaching 53.6% sisään 2022. This has had a certain impact on the development of the graphite bipolar plate industry.
