Abstract[English]
The invention at hand relates to an electrolysis cell, a process for the production of hydrogen by electrolysis and a cell stack comprising a multitude of the electrolysis cells, wherein each cell comprises an anode compartment, a cathode compartment and a separator, wherein a sealing member seals the electrolysis cell volume from the surrounding, the electrolysis cell electrolyte feed and/or electrolysis cell electrolyte outlet are located in the cell volume and comprise means for reducing stray currents.[French]
L'invention concerne une cellule d'électrolyse, un procédé de production d'hydrogène par électrolyse et un empilement de cellules comprenant une multitude de cellules d'électrolyse, chaque cellule comprenant un compartiment d'anode, un compartiment de cathode et un séparateur, un élément d'étanchéité scellant le volume de cellule d'électrolyse à partir de l'environnement, la sortie d'électrolyte de cellule d'électrolyse et/ou la sortie d'électrolyte de cellule d'électrolyse étant situées dans le volume de cellule et comprenant des moyens permettant de réduire les courants vagabonds.
