Woven wire mesh plays a significant role in the battery and fuel cell industry, providing various applications and benefits. Here are some ways woven wire mesh is utilized in battery and fuel cell systems:
Electrode Support: Woven wire mesh can be used as a support structure for electrodes in battery and fuel cell systems. It provides mechanical stability and helps maintain the structural integrity of the electrode assembly. The mesh also aids in current distribution and improves the overall performance of the battery or fuel cell.
Current Collection: Woven wire mesh is employed as a current collector in battery and fuel cell electrodes. It serves as a conductive pathway for the flow of electrons, enabling efficient transfer of electrical current within the cell. The mesh’s high electrical conductivity and open structure facilitate uniform current distribution across the electrode surface.
Gas Diffusion Layers: In fuel cells, woven wire mesh is utilized as a gas diffusion layer (GDL). The mesh acts as a conductive and porous substrate that allows the efficient diffusion of reactant gases, such as hydrogen and oxygen, to the electrode surfaces. It promotes gas flow, aids in water management, and enhances overall cell performance.
Separator Support: Woven wire mesh can be employed as a support structure for separators in battery and fuel cell systems. It helps to maintain the physical integrity of the separator, preventing its collapse or deformation under operating conditions. The mesh also contributes to uniform electrolyte distribution and facilitates ion transport within the cell.
Filter and Protection: Woven wire mesh is used as filters or protective layers in battery and fuel cell systems. It can be applied to prevent the ingress of contaminants, such as particulates or impurities, into the cell. The mesh’s precise aperture size and filtration efficiency help maintain the purity of the electrolyte and improve the longevity and performance of the cell.
Heat Dissipation: Woven wire mesh with high thermal conductivity can be utilized for heat dissipation purposes in battery and fuel cell systems. By incorporating mesh layers in the design, excess heat generated during cell operation can be efficiently dissipated, enhancing thermal management and preventing overheating issues.
It’s important to note that the specific application and selection of woven wire mesh in battery and fuel cell systems may vary based on the specific requirements, cell design, and operating conditions. Different mesh materials, weaves, wire diameters, and specifications can be chosen to optimize performance and meet the unique needs of the application.
