Abstract: A method for producing an electrode arrangement for use in a fuel cell. The method includes providing a filament comprising a supporting core and a plurality of webs extending radially from the core, the filament forming a radially internal, electrically conductive first electrode; and pulling a woven stocking over the filament.

Abstract: A microreactor includes a filament comprising a supporting core having an axial length and a plurality of webs extending radially from the core and axially along said length. The filament forms a radially internal, electrically conductive first electrode. The microreactor also includes a radially external membrane having a radially internal envelope surface separated from the core by the webs, thereby forming flow channels in which a fuel component flows against the filament.

Abstract: A microreactor for use in an electrode system of a fuel cell includes a filament having a supporting core and a plurality of spokes extending radially from the core, the filament forming an electrode against which a fuel component flows. A membrane is supported on the spokes to form flow channels for the fuel component, the filament and the membrane supporting each other.

Abstract: The aim of the invention is to provide a mechanically stable microreactor that can be subjected to high electrical loads and that is used in an electrode system of a fuel cell. To this end, a fuel component flows towards a filament (98) through at least one flow channel (102). Said filament is configured as a radially inner electroconducting electrode of the microreactor (97) and is linked with a radially outer membrane (101), the two structures supporting one another. The radially inner peripheral surface of the membrane (101), at least in some sections, is spaced apart from a supporting core (55) of the filament (98) by spokes (100), thereby forming at least one flow channel (102).
