High Performance Long Life Air Diffusion Electrodes (ADEs)

Metal-air batteries and alkaline fuel cells are each the subject of continued research due to their high theoretical energy density, high level of safety and reduced costs. Bettergy produces long-life air diffusion electrodes (ADEs) for metal air batteries and fuel cells. Our high performance ADEs have the following performance characteristics and can be tailored to meet customer specifications.


  • High current capability  (> 500 mA/cm2)
  • Proven long life (> 12,000 hrs demonstrated)
  • Low cost non-precious metal catalyst

Bifunctional ADEs are also available. 


  • Metal air batteries in alkaline and neutral electrolyte
  • Alkaline fuel cells and alkaline membrane fuel cells
  • Lithium air batteries
  • Metal hydride air batteries¬†
  • Air reduction-based chlor-alkali electrolysis
