本发明涉及一种金属/空气电池阴极（1），其包括由活性材料制成并具有空气侧（A）和金属侧（M）的至少一个活性层（2），集流体 （3）以及由疏水材料制成并沉积在活性层（2）的空气侧（A）上的疏水膜（4）。 所述疏水性材料具有多孔结构并已渗透到活性层（2）的空气侧（A）中，从而在疏水性膜（4）和活性层（2）之间形成相互渗透区（ Z）的活性材料中的疏水材料，其中疏水材料的浓度梯度在阴极中空气的进入方向上减小。

The invention relates to a cathode (1) metal / air cell comprising at least one active layer (2) made of an active material and having an air side (A) and a metal side (M), a current collector (3), and a hydrophobic membrane (4) made of a hydrophobic material and deposited on the air side (a) of the active layer (2). Said hydrophobic material has a porous structure and has penetrated the air side (A) of the active layer (2) so as to form, between the hydrophobic membrane (4) and the active layer (2), an interpenetration zone ( Z) of hydrophobic material in the active material in which is a hydrophobic material concentration gradient descending in the incoming direction of air into the cathode.
