Naked Platinum (Pt) Mesh Electrode (52–200 Mesh) – Custom Cut

Naked platinum (Pt) mesh is a high-purity, woven-wire electrode material used as a chemically stable, high-conductivity counter electrode or current collector in advanced electrochemistry. The mesh architecture increases effective surface area and promotes uniform current distribution compared with flat foil, making it ideal for gas-evolving and high-current-density experiments such as water electrolysis.

Working Principle

In an electrochemical cell, the Pt mesh typically serves as a counter electrode (or sometimes a robust current collector). Its noble-metal surface enables fast electron transfer while resisting corrosion across a wide electrochemical window. The open weave improves electrolyte access, reduces concentration polarisation near the electrode, and allows gas bubbles (H₂/O₂) to detach more readily, supporting stable polarisation behaviour at elevated currents.

Key Specifications (Customisable)

• Material: Platinum (Pt), high purity (commonly 99.9–99.99%)
• Mesh options: 52, 80, 100, 200 mesh (mesh = openings per inch)
• Construction: Woven wire cloth; plain weave commonly available
• Cut formats: Custom shapes and sizes (squares, strips, discs) on request
• Typical integration: Spot-weld/clamp to Pt wire, nickel wire, or suitable current lead (application dependent)
  
  

Compatibility & Handling Notes

• Compatible with most aqueous acids and alkalis used in electrochemistry and electrolyser testing.
• Avoid aggressive Pt-dissolving media (e.g., aqua regia) and take care in chloride-containing electrolytes at high anodic potentials where Pt dissolution/complexation can increase.
  
  

Typical Applications

• Water electrolysis (PEM/AEM/alkaline research cells)
• Fuel cell and electrolyser half-cell testing
• Electrocatalyst screening and durability protocols
• Photoelectrochemistry (stable counter electrode with low contamination risk)
• Sensors and general electrochemical testing as a reproducible inert electrode
