Distribution structure for providing at least one reaction gas

Abstract

The invention relates to a distribution structure (10) for providing at least one reaction gas, in particular a gas mixture containing oxygen (O2), for a fuel cell (100) or an electrolyser, having a first structure element (11) and a second structure element (12), wherein the first structure element (11) and the second structure element (12) are designed and arranged with respect to one another such that: a distribution area (15) for the reaction gas is formed between the first structure element (11) and the second structure element (12); a plurality of feed channels (16) branch off from the distribution area (15) and are orientated substantially perpendicular to the distribution area (15); and a plurality of discharge channels (17) are formed below the second structure element (12) and are orientated parallel to the distribution area (15).

Description

technical field

[0001] The invention relates to a distributor arrangement for supplying a fuel cell or an electrolysis device with at least one reaction gas, in particular an oxygen-containing gas mixture, according to the preamble of the independent device claim. The invention also relates to a fuel cell or electrolysis device according to the preamble of the independent independent device claim, for example having a polymer membrane for transporting protons or hydroxide ions. Background technique

[0002] Fuel cells and electrolyzers are electrochemical energy converters. In fuel cells, for example, hydrogen and oxygen are converted into water, electricity and heat. In contrast, water is split, for example, into hydrogen and oxygen by means of an electric current. A plurality of fuel cells can also form a battery pack, a so-called stack. Reactants comprising hydrogen, oxygen in the case of fuel cells and water in the case of electrolyzers, as well as cooling liquid are ...
