[0027] FIG. 1A illustrates an exemplary view of an electrolyzer unit, in accordance with an embodiment of the present disclosure.
[0028] Referring to FIG. 1A and FIG. 1B, hydrogen generation system 100 (also referred to as a system 100, herein) using alkaline water electrolysis, where the system 100 maximizes hydrogen production efficiency while ensuring high-purity output and operational safety. The system 100 includes an electrolyzer unit 102, which is the core component responsible for hydrogen generation through alkaline water electrolysis. The electrolyzer unit 102 includes a vertical cylindrical transparent chamber 104, allowing visual inspection of the electrolyte level and gas formation. Inside the chamber 104 is an electrode plate stack 106 defining a series of stainless steel plates arranged in close parallel configuration. These series of stainless steel plates act as the anode and cathode. The electrode plate stack 106 can be immersed in an alkaline electrolyte solution, typically a hydrogen hydride (HH⁺) solution, which facilitates efficient ion transport during electrolysis. At the top of the electrolyzer unit 102, there is a cap 108 housing the electrical terminals, which supply DC power to the electrode plate stack 106. Upon application of voltage, hydrogen gas is released at the cathode and oxygen at the anode, creating a mixed gas stream inside the chamber 104. The electrolyzer unit 102 can be configured to optimize electrochemical efficiency by maximizing electrode surface area and ensuring effective ion mobility in the electrolyte.
[0029] FIG. 1B illustrates an exemplary view of an oxygen trap unit, in accordance with an embodiment of the present disclosure. The oxygen trap unit 110, which plays a critical role in purifying hydrogen gas stream by removing residual oxygen. The oxygen trap unit 110 includes vertical transparent cylindrical container 112 with a top cap 114 for sealing and inlet/outlet connections or inlet/outlet pipe. A gas delivery pipe 116 extends from the top and is submerged into the distilled water inside the container 112. Oxygen contamination can arise from imperfections in the separator, operational variations, or gas crossover between the anode and cathode chambers. If unfiltered, even trace oxygen content in the hydrogen stream can lead to combustion risks and reduce the efficiency of hydrogen-based systems. To overcome the above limitations, the oxygen trap unit 110 operates by leading the gas mixture of hydrogen and oxygen through the container 112 of distilled water. Depending on its higher solubility in water, oxygen gets dissolved while hydrogen, being lighter and less soluble, is released in the form of bubbles and collected for further use.
[0030] The gas mixture from the electrolyzer unit 102 containing both H₂ and O₂ enters through the gas delivery pipe 116 and bubbles through the water. The oxygen is more soluble in water than hydrogen, it gets absorbed, while hydrogen escapes as visible bubbles, exiting through the outlet pipe at the top. This simple but effective solubility-based separation ensures that only high-purity hydrogen proceeds to the next stage. The oxygen trap unit 110 thus enhances system safety and improves the quality of hydrogen collected for usage or storage.
