Electric Fuel Air Electrodes
High Performance & Low Cost for Metal Air Batteries and Fuel Cells
The Electric Fuel Air Electrodes are designed for oxygen reduction in both low and high power applications. The E-4 and E-4B Air Cathode are Manganese based and currently used in commercial applications in various alkaline primary batteries. Both can be used in metal-air batteries, AFCs, DBFCs, air depolarized batteries, or any application requiring gas diffusion electrodes.
Electric Fuel has been producing Air Electrodes for over 20 years for a large range of diverse applications from pocket chargers to electric vehicles.
