Abstract

The invention relates to a distribution structure (10) for an electrochemical cell (30) for supplying a cell element (1) with a fluid medium (M). The distribution structure comprises a fluid inlet (11), which branches into a number of N distribution stages, wherein a distribution channel (12) is divided into two channels of smaller cross section in the main flow direction (S) from one stage (K) to the next stage (K+1), and wherein the distribution channels (12) of the N-th stage of the distribution structure (10) are configured so that the fluid medium (M) is distributed evenly over a width of the cell element (1). The invention further relates to an electrolyser or a corresponding component lighting system comprising the distribution structure.
