The invention relates to a metal-air electrochemical cell comprising a frame () defining an electrolyte chamber having an anode side and a cathode side, wherein an air cathode assembly is provided in the cathode side, said air cathode assembly () comprising hydrophobic porous film having a first face and a second face, with current collector () and catalyst-containing active layer () provided on said first face, with the planar dimensions of the catalyst-containing active layer on said first face being smaller than that of said hydrophobic film and said current collector, such that the catalyst-containing active layer does not reach the edges of said hydrophobic film and said current collector, thereby creating a catalyst-free margin () on the hydrophobic film () and current collector which surrounds the catalyst-containing active layer, and wherein said first face of the hydrophobic film and said frame of the cell arm joined together by thermoplastic () applied onto the catalyst-free margin of the hydrophobic film. A method of assembling the metal/air cell is also described.
