Recently, Yihuatong's independently developed "An Online Activation Method and Device for a Fuel Cell System" passed the review of the Australian Intellectual Property Office and officially obtained an Australian standard patent grant, with the patent number AU 2022350248. This achievement is the first Australian invention patent obtained by the company in the core technology field of fuel cells, indicating that its relevant innovative technology has further gained recognition from authoritative institutions outside China.
The patent entered the Australian national phase through the Patent Cooperation Treaty (PCT) international application system. After completing international search, patentability assessment, and local examination procedures, it was ultimately granted. The related technology is a core achievement formed by Yihuatong's R&D team through three years of continuous research and development, primarily aimed at proposing solutions to issues such as long activation times for fuel cells and performance degradation and reduced service life caused by impurities.
According to reports, this technology can improve the activation efficiency of fuel cell systems and enhance product operational stability. Currently, related results have been applied to fuel cell commercial vehicles in Australia and the Brisbane distributed generation project, further verifying the technology's application capability in real-world scenarios.
As a technology enterprise in the hydrogen energy field, Yihuatong continuously promotes independent R&D of core technologies and global intellectual property layout, and focuses on application scenarios such as transportation, energy storage, and comprehensive carbon neutrality to improve the green technology system across the entire chain of "production, storage, and utilization." The company has also built a multidisciplinary R&D team covering directions such as hydrogen production, energy storage, and fuel cells, as well as innovation platforms including the Beijing Engineering Technology Research Center, Beijing Key Laboratory, and Beijing Enterprise Technology Center.
As of the end of June 2026, Yihuatong had cumulatively obtained over 1,200 granted patents, including over 480 invention patents. These patents cover fields such as fuel cell system design, control strategies, and structural design, and extend to technology directions like energy storage scheduling, energy balancing, and thermal safety, further improving the company's independent intellectual property system.
