Air depolarized electrochemical cells are formed having a cell construction for improving or enhancing air flow to an air electrode. The electrochemical cell includes a layer of material disposed between a positive air electrode and an inner surface of a base of a cell casing, and having a surface facing the base, with the layer of material being an air permeable, hydrophobic layer or an air and water permeable layer. At least one of the inner surface of the base and the surface of the layer of material facing the base comprises at least one projection or at least one groove or a combination thereof whereby an open air channel is provided between the inner surface of the base and the layer of material, with the air channel being in contact with at least one air aperture of the cell. Methods for producing air depolarized electrochemical cells having air flow channels are disclosed.
