Resumen de: WO2025179506A1
The present disclosure relates to an electrode separator unit, a preparation method, an electrolytic cell unit, and a device for hydrogen production from a renewable energy. The electrode separator unit of the present disclosure comprises a membrane electrode assembly arranged in a center area of the electrode separator unit and comprises a sealing frame arranged around the outer peripheral wall of the membrane electrode assembly, wherein the inner peripheral wall of the sealing frame is fixedly connected to the outer peripheral wall of the membrane electrode assembly by means of material connection. In the solution of the present disclosure, by using the sealing frame and fixedly connecting the inner peripheral wall of the sealing frame to the outer peripheral wall of the membrane electrode assembly by means of material connection, no gaps generated by traditional packaging are present in the electrode separator unit. In addition, the contact area between the sealing frame and an adjacent functional component during fixed connection is increased, so that the clamping force for packaging an electrolytic cell device is more concentrated, and thus the sealing effect of the electrode separator unit is firmer, thereby further improving the hydrogen production efficiency. In addition, the present disclosure further reduces the number of parts, reduces the production cost, and improves the production efficiency.

Resumen de: WO2026207618A1
An electrolyzer system and associated design and optimization methods are disclosed for producing hydrogen gas from an impure wastewater feedstock. Electrode temperature mapping and analysis of thermoelectric phenomena, including Joule/Thomson effects in homogeneous conductive electrodes such as 316L stainless steel, are used to identify localized oxidation and reduction regions and correlate them with gas bubble nucleation and detachment. These findings, together with electrode material characteristics and operating conditions, are incorporated into computational fluid dynamics modeling of two-phase gas–liquid flow to predict electrode and flow-field configurations that improve bubble removal, reduce overpotential and resistive losses, and enhance heat and mass transfer. In some embodiments, optimized electrodes include microchannel networks configured to direct electrolyte toward preferential reaction sites and promote gas disengagement. The resulting systems can achieve energy consumption and hydrogen production rates using contaminated wastewater comparable to systems operating on purified, demineralized water.
