Title:
ELECTROLYSER AND METHOD FOR OPERATING AN ELECTROLYSER
Document Type and Number:
WIPO Patent Application WO/2023/186359
Kind Code:
A3
Abstract:
The invention relates to an electrolyser (1) for generating hydrogen (H2) and oxygen (O2) as product gases, said electrolyser comprising an electrolysis module (3) and a gas separator (5) which is designed for phase separation of the product gas from water, the electrolysis module (3) being connected to the gas separator (5) via a product flow line (7) for the product gas, and a return line (9), which connects the gas separator (5) to the electrolysis module (3), being provided for the separated water. The gas separator (5) is designed and positioned at a height difference (Δh) above the electrolysis module (3) in such a way that, in the event of a standstill, the electrolysis module (3) can be automatically flooded with water, driven solely by the height difference (Δh). The invention also relates to a method for operating an electrolyser (1) comprising an electrolysis module (3), wherein, in a standstill mode, the electrolysis current is stopped and a safety deactivation is initiated.
