2022-11-09 14:36

Suzhou Xingran Technology Co., Ltd. was established in 2021 and is an innovative technology enterprise specializing in the R&D, production, and sales of hydrogen-generation equipment via water electrolysis. In 2015, the company’s founder set up a hydrogen energy research studio in Guangdong, aiming to achieve in-depth development of PEM electrolyzers and hydrogen fuel cells. The studio specifically hired foreign experts to focus on the R&D of membrane electrodes, and in 2021, the studio made a significant breakthrough in the development of perfluorosulfonic acid proton exchange membranes.

Our newly developed, independently researched and developed PEM water electrolysis hydrogen production equipment can achieve hydrogen production rates ranging from 0.5 m³/h to 1,000 m³/h, with a hydrogen production efficiency of up to 78%–84% and a hydrogen purity of up to 99.999%.

The independently developed hydrogen production system management system for water electrolysis achieves automatic control of parameters such as electrolyzer pressure, temperature, liquid level, and alarm interlocks, effectively safeguarding the operation of the electrolyzer and extending its service life by more than 300%.

Innovation Highlights of Xingran’s PEM Water Electrolysis Hydrogen Production Technology:

1. The ordered membrane electrode technology developed by Xingran significantly enhances catalyst utilization, increasing the active surface area by more than 50% compared to conventional membrane electrodes. By employing an array of catalysts, it also improves electron conductivity. As a result, energy consumption has been reduced from 4.8 kWh/m³ to 4.2 kWh/m³, representing an efficiency improvement of 11%. Moreover, its resistance to high-potential corrosion enables the electrolyzer to operate normally at higher potentials.

2. The core component, the PEM electrolyzer, adopts a zero-gap design, increasing overall efficiency from 73% to 84%. While maintaining strong sealing performance, this design also enhances assembly efficiency. The uniformity of water flow within the electrolyzer has been optimized, effectively improving the utilization rate of the membrane electrode. Additionally, the service life has been extended from 20,000 hours to 60,000 hours.

Xingran Technology’s hydrogen production equipment project, with a total investment of 500 million yuan, has been established in Changzhou, with an annual output value of 5 billion yuan.
