Absstract of: US2022251721A1

A method of preparing an ionomer of an ion exchange membrane with a recombination catalyst to prevent gas crossover of species, such as hydrogen and/or oxygen, to anodic and cathodic cell compartments of an electrochemical cell. An ionomer of an ion exchange membrane is prepared with a recombination catalyst. The ionomer is a proton or anion exchange polymer and the recombination catalyst, selected from the precious metals group, is provided in ionic form in a liquid metal salt solution. The ion exchange membrane is immersed into the liquid metal salt solution to exchange ionic ionomer ports with the ionic form of the recombination catalyst. The membrane is then assembled in the electrochemical cell and the ionic form of the recombination catalyst is at least partly reduced to metallic form by forcing hydrogen to permeate through the ionomer of the ion exchange membrane.

PARTICULARLY COMPACT AND EFFICIENT ASSEMBLY WITH SEPARATOR AND ELECTRODES TO BE USED IN THE ELECTROLYSIS OF WATER FOR THE PRODUCTION OF HYDROGEN AT HIGH PRESSURE

Publication No.: WO2022167880A1 11/08/2022

Applicant:

CTS H2 S R L [IT]

Absstract of: WO2022167880A1

The present invention is relative to a separator/electrodes assembly to be positioned within an appropriate electrolytic cell for the production of hydrogen at high pressure, alternative to the classic MEA, provided with a particularly compact and sturdy structure that makes it possible to achieve an excellent efficiency of the system. In practice, the structure is designed to reduce, or even eliminate the so-called "crossover" of oxygen into the hydrogen and vice-versa, so as to allow the increase in pressure directly in the cell, without compressors, and to facilitate its production and the maintenance operations, thanks to the fact that the apparatus consists of a single metallic piece (One Piece Core, "OPC"). This apparatus is used in the scope of the "AES" (Solid State Alkaline) technology, which shares the principles of the alkaline polymeric membrane (AEM) technology, without resorting to the use of polymeric membrane.
