E-4 & E-4A Air Cathode

The Electric Fuel E-4 and E-4A Air Electrodes are designed for oxygen reduction in both low and high power applications. The E-4 Cathode is currently used in commercial applications in various alkaline primary batteries requiring high power. It can be used in metal-air batteries, AFCs, DBFCs, air depolarized batteries, or any application requiring gas diffusion electrodes.

The E-4A Cathode was recently developed to reduce corrosion in metal-air cells. Its specifications and pricing are the same as the E-4 Cathode.

Through our Engineering Services, we can work with the customer to customize our Air Electrode for your application, as well as advise on the use of the Air Electrode including:

• cutting, bending and punching the Air Electrode
• sealing the edge of the Air Electrode
• attaching to the Air Electrode to draw current
• optimizing the color of the Teflon to fit your environmental requirements and high current requirements
• optimizing the other components in the Air Electrode for your application
