Improving Fuel Cell Performance

As fuel cell technology for aerospace, transportation, material handling, and backup power systems continues to advance, design engineers are constantly looking for ways to improve efficiency and cost. This has led to costly materials like Nickel, Niobium, Silver, Titanium, and Zirconium frequently being used for electrolyzer, PEM, and SOFC fuel cells. This can get very expensive for traditional chemically etched or perforated materials and increase the weight of the fuel cell. Woven wire mesh materials and other products that require manufactured connection points decrease conductivity and increase resistance across the system resulting in reduced efficiency in the fuel cell. These materials can also shift and move under pressure during fuel cell usage causing changes in the mesh spacing and resulting in even further performance degradation. How can today’s engineers improve the overall design of their next-generation fuel cells?

CThru Mesh® Precision Expanded Metals Increase Fuel Cell Efficiency

CThru Mesh® precision expanded metals reduce fuel cell cost as it produces 90% less waste in the manufacturing process, offers a continuous structure for maximum electrical conductivity across the system, and reduces overall weight while providing additional structural support to reduce flex in the fuel cell membrane resulting in peak output performance. That’s why engineers across the world turn to CThru Metals to help produce their Current Collector Screens, Flow Field Structures, Gas Diffusion Electrodes, and Membrane Support Grids for their latest fuel cell designs.
