Gas Diffusion Layer

  • 主要用途 2cmX2cm / 5cmX5cm / 10cmX10cm / 20cmX20cm

0.3 mg/cm² 40% Pt on Carbon Cloth Electrode

Fuel Cell Earth offers anode and cathode electrodes, Our electrodes consist of a precious metal catalyst loaded onto a Teflon treated gas diffusion backing layer. The electrode is hydrophobic to help reduce the potential flooding issue of a functioning fuel cell. We use Platinum/Carbon catalyst. Our backing layer consists of carbon paper or carbon cloth.

This loading is often used in cost sensitive Hydrogen / Air Fuel Cells or other electrochemical systems.
