Abstract

Two electrodes (2,4) and an intermediate ion exchange membrane (3) form a fuel cell of tubular form. The H2 electrode (2) is the innermost electrode and is surrounded by the membrane and then the O2 electrode. The H2 electrode forms a central H2 inlet (1) and a gas-permeable protective sheath (5) can be provided on the outside of the assembly. O2 e.g. from the air passes to the O2 electrode through the sheath.

Description

Die Erfindung betrifft eine Brennstoffzelle nach dem Oberbegriff des Anspruches 1. Brennstoffzellen als solche sind bekannt.The invention relates to a fuel cell according to the preamble of claim 1. Fuel cells as such are known.

Die Herstellung solcher Brennstoffzellen ist aufwendig (Gehäuse, Elektroden aus z. B. Kohlenstoff, Titan oder Austenit).The manufacture of such fuel cells is complex (housing, electrodes made of e.g. As carbon, titanium or austenite).

Der Erfindung lag die Aufgabe zugrunde, eine Brennstoffzelle anzugeben, die ma­ schinell und damit kostengünstig herzustellen ist.The invention had for its object to provide a fuel cell, the ma is quick and therefore inexpensive to manufacture.

Die Aufgabe wird durch die Merkmalskombination des Patentanspruchs 1 gelöst.The object is achieved by the combination of features of patent claim 1.

Vorteilhafterweise kann eine erfindungsgemäße Brennstoffzelle z. B. mit Extrudierver­ fahren in mehreren Schritten hergestellt werden. Das zunächst in langen Einheiten hergestellte schlauchförmige Teil (Schlauch mit mehreren Schichten) kann in appli­ kationsspezifische Längen (Meterware) unterteilt, z. B. geschnitten, eingesetzt wer­ den.A fuel cell according to the invention can advantageously, for. B. with Extrudierver drive can be manufactured in several steps. Initially in long units The tubular part (tube with several layers) can be produced in appli cation-specific lengths (sold by the meter), e.g. B. cut who used the.

Die Brennstoffzelle kann auch umgekehrt als Elektrolyseur betrieben werden.The fuel cell can also be operated in reverse as an electrolyzer.

Die Brennstoffzelle nach der Erfindung wird anhand der Zeichnung näher beschrie­ ben.The fuel cell according to the invention is described in more detail with reference to the drawing ben.

Die Brennstoffzelle, die z. B. luftatmend ist, besteht aus einer rohrförmigen elektrisch leitenden Wasserstoff-Elektrode 2 mit einem Wasserstoffeinlaß 1, die konzentrisch an liegend umgeben ist von einer beidseitig mit Katalysator beschichteten Ionenaus­ tauschmembran 3.The fuel cell, the z. B. is air breathing, consists of a tubular electrically conductive hydrogen electrode 2 with a hydrogen inlet 1 , which is surrounded concentrically to lying by a bilaterally coated with catalyst ion exchange membrane 3rd

Diese Membran ist ebenfalls konzentrisch an liegend mit einer elektrisch leitenden Luft/Sauerstoff-Elektrode 4 umgeben. Abschließend kann ein gasdurchlässiger Schutzschlauch 5 angebracht sein.This membrane is also concentrically surrounded by an electrically conductive air / oxygen electrode 4 . Finally, a gas-permeable protective tube 5 can be attached.

Der Wasserstoff wird axial in die Wasserstoffelektrode 1 eingeführt. Der Sauerstoff wird, z. B. aus der Luft, radial von außen zugeführt.The hydrogen is introduced axially into the hydrogen electrode 1 . The oxygen is e.g. B. from the air, radially from the outside.

Es kann auch der benötigte Sauerstoff (Luft) durch ein weiteres konzentrisch ange­ ordnetes Rohr (Schlauch) axial zugeführt werden, von wo er radial eindringt.The required oxygen (air) can also be concentrated concentrically by another ordered pipe (hose) are fed axially, from where it penetrates radially.
