摘要： The invention relates to a gas electrode that comprises a plurality of stacked layers (2, 3, 4), wherein the first layer (2) is in contact with a solid substrate (1) while the last layer (4) has a free outer surface to be contacted with a gas, each layer being made of at least one mixed oxide selected from the group including perovskites and Ruddlesden-Popper phases, the micro-structure of the first layer (2) being different from that of the last layer (4), the porosity of the different layers (2, 3, 4) increasing from said first layer (2) towards said last layer (4), and the different layers stacked on each other defining a network of a solid interconnected material between the free outer surface of the last layer (4) and the solid substrate (1) with a total thickness higher than 1 μm. The invention also relates to a method for making such an electrode and to the use thereof in an electrochemical cell.
