Research Project of Weifang FuYuan Turbocharger Co., Ltd. Passes Scientific and Technological Achievement Evaluation

On January 11, 2019, Zhongke Hechuang (Beijing) Scientific and Technological Achievement Evaluation Center, a professional third-party evaluation body, convened experts in Jinan to evaluate the "air-bearing centrifugal compressor for fuel cells" project completed by Weifang FuYuan Turbocharger Co., Ltd. The evaluation followed the Ministry of Science and Technology's Measures for Science and Technology Evaluation and the standards and procedures for evaluating scientific and technological achievements, on the principles of scientific rigor, independence, objectivity and impartiality.

The expert panel comprised Professor Yu Mingjin of Shandong Jiaotong University, Professor Zhang Jinsheng of Shandong University, Senior Engineer Zhang Cunsheng of the Shandong Mechanical Design and Research Institute, Professor Dong Mingxiao of Shandong Jianzhu University, Research Fellow Lin Jianghai of the Shandong Mechanical Design and Research Institute, Professor Wang Renren of Qilu University of Technology and Research Fellow Zhang Zongyu of the Energy Research Institute of the Shandong Academy of Sciences.

After review, the experts concluded that the project had developed an innovative air-bearing centrifugal compressor to meet the special air-supply requirements of fuel cells, with the following technical features and innovations. The compressor integrates an aerodynamic air bearing, a centrifugal impeller, a high-speed permanent-magnet synchronous motor and a variable-frequency controller, giving automotive fuel cells a reliable source of clean air with a wide flow range and a broad high-efficiency operating region. The purpose-developed high-speed permanent-magnet synchronous motor and its control system are efficient, energy-saving and smooth-running. The impeller is coupled directly to the motor, which gives a compact design. Prototype testing showed that the main technical performance indicators are advanced, and user feedback has been good. The project is notable for its integrated innovation and has broad market prospects, and its main technical performance indicators have reached an internationally advanced level. After a full review by the expert panel, the experts present agreed unanimously that the "air-bearing centrifugal compressor for fuel cells" project had passed the scientific and technological achievement evaluation.
