CNC Machined Fuel Cell End Plate Custom Precision OEM Manufacturing

CNC Machined Fuel Cell End Plate Custom Precision OEM Manufacturing. Aluminum alloy/titanium alloy + topologically optimized weight-reduction design; end plates are 30%-50% lighter, enhancing the stack's overall power density. Titanium alloy or 316L stainless steel combined with electropolishing and passivation treatments ensures extremely low metal ion leaching, protecting the MEA and catalyst. Micrometer-level flatness control of sealing surfaces + precision machining of sealing grooves, ensuring zero leakage in the hydrogen, air, and water pathways. End plates can integrate multiple flow channel interfaces, sensor mounts, and tie-rod structures, reducing the number of parts and assembly steps.
