The invention relates to a method and a device for producing elementary oxygen or for increasing the concentration thereof in the inhaled air of a user. According to the invention, water is split into hydrogen and elementary oxygen by means of electrical energy (electrolysis), the elementary oxygen is mixed with the inhaled air, and the hydrogen is mixed with the surrounding air in order to be converted back into water (fuel reaction). The splitting of the water into hydrogen and elementary oxygen and the conversion of the hydrogen and surrounding air into water take place simultaneously and continuously, forming a reaction circuit, and are coupled to each other, the electrical energy produced during the conversion being used to reduce the energy demand for the splitting. To this end, an electrolyzer outfit for splitting water into hydrogen and elementary oxygen, and a fuel cell for converting the hydrogen and the surrounding air into water are electrically connected in such a way that they can conduct liquids.

Method and device for producing oxygen

An electrode configuration for field cages, especially in microsystems, comprises a large number of electrodes in which an electrical potential can be applied to each end region through a feed region. The end region is arranged to form the field cage and inhomogeneous shielding fields outside the field cage. To reduce thermal convection, the feed region has a strip form whose width is substantially smaller than characteristic dimensions of the end region.

The invention relates to the production of thin metal layers and structures thereof on substrates of various structures. The lateral extent of a metal layer on the respective substrate can be prescribed with a precision in the micron and submicron range. The method described makes it possible to manufacture flat and three-dimensional metal structures on smooth planar or curved surfaces, as are required, for example, for depicting writing or drawings. The method uses no printing techniques.
