Title
(EN) ELECTROLYSIS SYSTEM WITH CONTROLLED THERMAL PROFILE
(FR) SYSTÈME D'ÉLECTROLYSE À PROFIL THERMIQUE CONTRÔLÉ
Abstract
(EN)
This invention relates to a system comprising one or more electrolysis cell(s) and at least one power electronic unit that supplies the cell(s) with a fluctuating voltage, and to a method for operating one or more electrolysis cell(s), comprising providing one or more voltage fluctuations to the electrolysis cell(s) by at least one power electronic unit, enabling the provision of a low-cost electrolysis system which simultaneously allows for fast-response dynamic operation, improved electrolysis efficiency, increased lifetime and high impurity tolerance.
(FR)
La présente invention concerne un système comprenant une ou plusieurs cellule(s) d'électrolyse et au moins une unité électronique de puissance qui alimente la cellule/les cellules avec une tension fluctuante, et un procédé pour faire fonctionner une ou plusieurs cellules d'électrolyse, comprenant la fourniture d'une ou de plusieurs fluctuations de tension à la/aux cellule(s) d'électrolyse par au moins une unité électronique de puissance, permettant la fourniture d'un système d'électrolyse à faible coût qui permet simultanément un fonctionnement dynamique à réponse rapide, une efficacité d'électrolyse améliorée, une durée de vie accrue et une tolérance aux impuretés élevée.
