After 991 days and 23,784 hours of relentless exploration, the Okevi team has meticulously refined its innovations over more than a thousand days and nights, culminating in the official granting of two patents for its independently developed core technologies: “Electrolytic Structure and Hydrogen-Production Device” (Patent No.: ZL 2025 1 0163125.4) and “A Hydrogen-Production Device” (Patent No.: ZL 2025 1 0164590.X). These patents have now been formally authorized by the China National Intellectual Property Administration. This milestone is not only the result of sustained effort but also a testament to the team’s unwavering commitment to technological excellence.

01  Electrolysis Structure and Hydrogen Production Unit

　　The design comprises an electrolysis unit and an external sealing assembly, in which the coordinated configuration of an elastic sealing ring and a support ring optimizes the axial thickness, thereby ensuring outstanding sealing performance and effectively preventing leakage.

02  A patent for a hydrogen production device

　　By integrating the electrolytic structure with the clamping mechanism and incorporating a coordinated adjustment assembly for the positive and negative electrode pressure plates, while optimizing the interface layout and sealing configuration, the overall seal integrity and operational reliability of the device are significantly enhanced.

　　This is not only a prestigious honor but also an authoritative validation of our independent R&D capabilities and technological sophistication. Our innovative achievement has successfully bridged a major technological gap: we have overcome the challenging high-voltage structural design of electrolyzers, achieving a breakthrough from “high-voltage cells” to “high-voltage stacked cells.” This has endowed hydrogen production systems with more stable and efficient high-voltage output performance, thereby substantially addressing a core bottleneck in the industry.

The path of innovation is endless.

　　Looking ahead, Oceve will continue to harness technology as its plow and intelligence as its fertile soil, steadily increasing R&D investment to continuously enhance the core competitiveness of its products. The company will deepen collaboration with more research institutions to jointly explore new application scenarios for PEM water electrolysis hydrogen production technology, while proactively expanding into international markets and gradually establishing a global sales and service network, with the goal of becoming a leading enterprise in the hydrogen energy technology sector. Oceve places great emphasis on talent development and team building, committed to cultivating a highly qualified, professional technical team that will lay a solid foundation for the company’s sustainable growth.
