Tehai Hydrogen Energy Detection (Baoding) Co., Ltd. has applied for a patent for a hydrogen leak detection method specifically designed for fuel cell vehicles equipped with fuel cell systems. This innovative method addresses the challenge of accurately pinpointing leak locations, as traditional sensors alone are insufficient for real-time detection.
According to information from the National Intellectual Property Administration, the patent, titled "<b>Method for Detecting Hydrogen Leaks in Fuel Cell Vehicles with Fuel Cell Systems</b>", was published under application number <b>CN 119833680 A</b> and was filed in <b>October 2023</b>.
The patent abstract indicates that the proposed method includes several steps: First, it retrieves the pressure decay value and hydrogen monitoring concentration from the first hydrogen supply pipeline. If the pressure decay value is less than or equal to a predetermined threshold and the monitoring concentration is also within acceptable limits, hydrogen is then delivered to a second supply pipeline, where further monitoring occurs. If the conditions in this second pipeline meet the specified criteria, the system will proceed to test a third supply pipeline. If this pipeline does not meet the preset leak conditions, it concludes that there is no leak in the fuel cell system; otherwise, it determines that a leak is present.
This method effectively resolves the issue of relying solely on hydrogen concentration sensors, ensuring greater safety during usage.
Established in <b>2022</b>, <b>Tehai Hydrogen Energy Detection (Baoding) Co., Ltd.</b> is based in Baoding and primarily engages in professional technical services. The company has a registered capital of <b>70 million RMB</b>. Data analysis from Tianyancha reveals that the company has participated in <b>20</b> bidding projects, has <b>16</b> trademark records, and holds <b>99</b> patents, in addition to possessing <b>1</b> administrative license.
