Abstract
The invention provides electrodes suitable for use as air electrodes, processes for their preparation and metal/air cells utilizing such electrodes as air cathodes. The invention relates to an electrode comprising a catalytically active layer applied on one face of a hydrophobic porous film and a conductive current collector pressed onto said catalytically active face, wherein at least a portion of the marginal area of said face is free from catalyst, and wherein a sealant is provided around at least part of the perimeter of said catalytically active layer, said sealant forming a coating onto the catalyst-free marginal area of said hydrophobic film.
