As one of the key components of PEM fuel cells, graphite plates are mainly used to separate the anode and cathode and act as current collectors. This ensures smooth flow of current between the electrode and current collector. The use of high-quality graphite sheets in PEM fuel cells can significantly improve the performance and efficiency of the fuel cell system.
The electrical conductivity of the graphite plates must be carefully controlled to ensure optimal performance of PEM fuel cells. The electrical conductivity of graphite plates is affected by several factors, such as the purity of the graphite material and the manufacturing process used to make the graphite plates.
In recent years, the development of new graphite sheets for proton exchange membrane fuel cells has focused on improving the material's electrical conductivity while maintaining the required mechanical properties. Some of the most innovative formulations include blends of graphite and carbon nanotubes, which have demonstrated excellent conductive properties.
The graphite sheets used in PEM fuel cells must also be durable and resistant to environmental factors such as high temperatures and corrosive chemicals. The use of high-quality graphite materials and advanced production processes help ensure the service life and reliability of the fuel cell system.
In summary, the use of conductive graphite sheets in PEM fuel cells is critical to achieve high performance and efficiency in these systems. Advances in technology and materials science have led to the development of new formulations that offer increased conductivity and durability, making them ideal for PEM fuel cell applications.
