[SMM Hydrogen Energy Brief: Dalian Institute of Chemical Physics' New Air-Cooled Stack Technology Passes Appraisal] On May 10, the high specific power cathode-closed air-cooled stack technology developed by the team of Academician Chen Zhongwei and Associate Researcher Zhang Meng from the National Key Laboratory of Energy Catalytic Conversion at Dalian Institute of Chemical Physics passed the scientific and technological achievement appraisal by China Petroleum and Chemical Industry Federation.
This achievement breaks through three core key technologies, effectively resolving the industry contradiction between water retention and oxygen mass transfer in air-cooled fuel cells, and solving technical challenges such as low humidity performance degradation, carbon corrosion, dry membrane flooding, and high power thermal management.
Currently, the team has construction completed a full-chain independent R&D system from materials and components to systems, holds 21 China invention patents, has established an automated production line and possesses large-scale delivery capability. Related products have been applied in fields such as agriculture and forestry operations, power inspection, and emergency rescue. Industrial drones equipped with this technology have achieved a driving range improvement of more than twice that of traditional batteries.
