AI Technical Summary

Problems solved by technology

Using an external recombiner greatly increases the H 2 cost of preparation, requires additional space that is not available inside the instrument, and can even be hazardous due to the hydrogen having to flow through the instrument from the unit to the recombiner

Abstract

The present invention relates to the field of generating gaseous hydrogen at high pressures and with high purity via electrolysis of water by means of an electrolyzer cell (100) with a novel structure.

Description

technical field [0001] The present invention relates to the field of production of gaseous hydrogen at high pressure with high purity by electrolysis of water. Therefore, the present invention also relates to a novel modular electrolysis unit for carrying out said electrolysis and a hydrogen production plant using this electrolysis unit. Background technique [0002] New hydrogen production technologies are moving towards the use of hydrogen as an energy carrier. Water electrolysis via a polymer electrolyte membrane (PEM) arranged between the cathode and anode plates is a promising technology for hydrogen production. A comprehensive review of water electrolysis. [0003] US Published Patent Application US2011 / 0266142A1 discloses a unitary electrolysis device for generating hydrogen at high pressure. According to one embodiment, the device comprises a pressure vessel, a water electrolysis unit and a water supply. A water electrolysis unit is mounted on or in the vessel an...
