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).
