A method for producing finely structured surfaces, in particular in plastics, includes a) applying at least one coating compound on at least one substrate; b) forming a fine structure by a die, which has the negative of a fine structure, c) curing the resultant finely structured coating compound, obtaining a substantially cured coating; and d) separating the finely structured coating from the die, wherein steps d) and c) can also be carried out in the reverse order.

Method for producing finely structured surfaces

The present invention pertains to a fuel cell with a storage unit () for storing hydrogen (H), with a proton conductive layer, which covers a surface of the storage unit (), and with a cathode () on a side of the proton conductive layer, which side is located opposite, wherein the storage unit () is directly coupled with an anode and/or the storage unit () is incorporated in a substrate () of a semiconductor. The storage unit () is preferably connected to the substrate () at least via a stress compensation layer ().

Fuel cell and proces for manufacturing a fuel cell

The invention relates to a sensor fuel cell that can be activated by a first substance (O) in its environment. The sensor fuel cell includes a catalytically active anode, a cathode that has a cathode surface at least partially exposed to the environment, and a proton-conductive membrane located between the anode and the cathode so as to convey protons through from the anode to the cathode. An anode surface of the anode is at least partially exposed to the environment for access of at least one second substance (H) from the environment to the anode. Such a disposition enables access of a first reactant in the form for example of oxygen from the ambient air to the cathode, and additionally access of a second reactant in the form for example of hydrogen from the ambient air to the free surface of the anode.

Sensor fuel cell

In a method for producing a proton-conductive, structured electrolyte membrane, particularly for a fuel cell, a coating, which comprises at least one ion-conductive cross-linking component having at least one acid group and at least one photoactive substances interacting therewith, is applied onto a solid body surface. The coating is optically masked in that at least one region of the coating, in which the electrolyte membrane is supposed to be, is exposed such that the cross-linking component cross-links with the photoactive substances to form a polymer and/or copolymer network adhering to the solid body surface. At least one unexposed region of the coating is removed in order to structure the electrolyte membrane.
