With the continuous development of hydrogen energy, the market has increasingly higher requirements for the specifications and performance of hydrogen fuel cells. In response to the market demand for hydrogen energy, new materials such as stampable bipolar plates, nano-scale Pt-graphite composite catalytic electrode materials, and new solid-state hydrogen storage materials have been developed.
－The stampable bipolar plates exhibit superior corrosion resistance, thermal conductivity, electrical conductivity, and mechanical strength compared to traditional bipolar plate materials. Additionally, the traditional manufacturing process of hydrogen fuel cell bipolar plates is complex and costly.
－The new nano-scale Pt-graphite composite catalytic electrode materials not only have high mass activity and high power density but also possess corrosion resistance, preventing fuel cell degradation within the low-temperature range of 50-80°C. These electrodes use low platinum load. Through the pulse electrochemical deposition (PECD) method, platinum nanoparticles are directly deposited on the surface of the gas diffusion layer (GDL), adopting a single-layer electrode structure, which significantly improves the utilisation of the platinum catalyst.
－The new solid-state hydrogen storage materials have a hydrogen storage capacity of 4-4.5 wt.%, comparable to the 70MPa high-pressure gaseous storage method, and can reduce the hydrogen release temperature to under 200°C.
－The development of these novel materials enhances the safety of hydrogen energy use, reduces energy consumption and costs, and has a profound impact on the transportation and energy industries.
