[0002] As an advanced sealing material, multi-layer graphite gaskets not only maintain the inherent superior properties of graphite bipolar plates but also significantly enhance their performance. They fully inherit the electrical and thermal conductivity of graphite, enabling them to efficiently transfer current and heat in sealed environments requiring electrical or thermal conductivity, reducing energy loss. Furthermore, their corrosion resistance and high chemical stability ensure long-term stability and reliability in environments with strong acids, bases, and corrosive media, reducing maintenance costs and replacement frequency. Multi-layer graphite gaskets utilize a specialized manufacturing process that significantly improves the mechanical properties and processability of graphite bipolar plates. The precise stacking and high-pressure treatment of each graphite layer not only enhances the gasket's overall strength and rigidity, but also imparts excellent elasticity and toughness, enabling it to better adapt to complex and changing operating conditions. Furthermore, the multi-layer structure allows for greater processing flexibility, allowing for customization of various shapes, sizes, and sealing requirements, thereby expanding its application range and market potential. In summary, multi-layer graphite gaskets, with their unique performance advantages, have become an indispensable sealing solution in modern industry.
