[Ten years of major development in chemical technology] 046-2023 Air compressor for hydrogen fuel cells

Thread Content

Chemical equipment has developed greatly in the past ten years. Praise for China's prosperity and strength in the prosperous age. It will be more lively and exciting with everyone's participation. Everyone is welcome to participate in more forum exchanges and discussions. Everyone pays attention to safety and knows how to respond to emergencies. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Recently, the HC08 air compressor for hydrogen fuel cells independently developed by Jiangzeng Heavy Industry, a subsidiary of China State Shipbuilding Corporation, passed the China Automotive Engineering Research Institute * * Gas vehicle engineering technology research center test inspection and China Classification Society type approval. 　　During the development process of the HC08 air compressor, the technical research and development team overcame the "stuck neck" technology in the hydrogen fuel cell field of "oil-free centrifugal air compressor". Through research on precision intelligent manufacturing processes and intelligent control algorithms based on neural network online parameter identification, we have achieved breakthroughs in core technologies such as precision aerodynamic bearing design, intelligent manufacturing processes for key components, and ultra-high-speed permanent magnet synchronous motor vector control strategies. We have successfully developed a wide-flow oil-free centrifugal compressor and an ultra-high-speed motor control system, which can meet the needs of a 60kW stack. 　　The successful development of the HC08 air compressor has effectively promoted the serial development of fuel cell air compressors at Jiangzeng Heavy Industry, accelerated the production capacity building of hydrogen fuel cell air compressors, and assisted the development and production capacity building of hydrogen fuel cell systems and their core components in Chongqing.
