Abstract[English]
The present invention relates to a method and system of producing hydrogen gas using a water electrolyser cell that comprises both a catalytic reactor and polymer electrolyte membrane (PEM) electrolyser stack of cells. Oxygen generated by the PEM electrolyser stack may be recycled. The system and method include controlling the concentration of hydrogen in the anode compartment of the PEM electrolyser stack by varying the amount of recycled oxygen.[French]
La présente invention concerne un procédé et un système de production d'hydrogène gazeux à l'aide d'une cellule d'électrolyseur d'eau qui comprend un réacteur catalytique et un empilement d'électrolyseurs à membrane électrolytique polymère (PEM) de cellules. L'oxygène généré par l'empilement d'électrolyseurs à PEM peut être recyclé. Le système et le procédé consistent à réguler la concentration d'hydrogène dans le compartiment de l'anode de l'empilement d'électrolyseurs à PEM en faisant varier la quantité d'oxygène recyclé.
