Abstract
An electrochemical cell for separating oxygen from the ambient air can be manufactured in a simple manner and inexpensively and both the electrodes and the electrolyte can be manufactured as thin layers. The electrochemical cell has a metallic housing plate (7), a gas-permeable carrier plate (11) located on the housing plate (7), a system of layers on the carrier plate (11), including a first electrode (13), an electrolyte (15) and a second electrode (17) exposed to the ambient air, wherein the oxygen generated is drawn off via a discharge opening at the housing plate (7).

An electrochemical cell for separating oxygen from a gas mixture which gas mixture contains oxygen as one of its components, the electrochemical cell comprising:
- a metallic housing plate;
- a porous gas-permeable metallic carrier plate located on said housing plate;
- a system of layers on said carrier plate, said system of layers comprising a first electrode layer, an electrolyte layer and a second electrode layer exposed to the gas mixture;
- and
- at least one discharge opening at said housing plate for drawing off the oxygen generated.
An electrochemical cell comprising:
- a porous gas-permeable metallic carrier plate;
- a first electrode layer on said carrier plate;
- an electrolyte layer on said first electrode layer;
- a second electrode layer on said electrolyte layer;
- and
- a housing plate connected to said carrier plate at one side of said carrier plate, said housing plate having a discharge opening for drawing off generated oxygen.
An electrochemical cell for separating oxygen from a gas mixture which gas mixture contains oxygen as one of its components, the electrochemical cell being formed by the steps of:
- providing a metallic housing plate;
- positioning a porous gas-permeable metallic carrier plate on the housing plate;
- providing a plurality of layers on said carrier plate comprising a first electrode layer, an electrolyte layer and a second electrode layer exposed to the gas mixture;
- and
- providing a discharge opening at said housing plate for drawing off the oxygen generated.
