Recently, the High-tech Division of the Ministry of Science and Technology organized the acceptance meeting for the “Key Technology Research on Reliability and Durability of Fuel Cell Backup Power System†of the “12th Five-Year†National 863 Plan in Beijing. The project was undertaken by Suzhou Forsail Energy Technology Co., Ltd., China Dongfang Electric Group Co., Ltd. and other units jointly completed. Through the implementation of the project, the modular redundant design of fuel cell backup power system stacks, fault prediction and diagnosis, and research on the safety and reliability of hydrogen were carried out; the reliability and durability evaluation methods for fuel cell backup power systems were established, and the direct current fuel was completed. Reliability and Durability Test of Battery Backup Power System Prototype. The membrane electrode preparation process was optimized, and the design, evaluation and evaluation of the electric stack, hydrogen supply, and hydrothermal management system were performed. A prototype of a 5kW (-48V) DC fuel cell backup power supply suitable for hot plugging was developed, with a single continuous operation capability. 36h, start and stop 506 times, accumulatively run 2100 hours; carried out fuel cell laminar sealing material design and preparation, bipolar plate structure design and preparation, end plate forming process and self-humidifying membrane electrode research; conducted self-humidification battery stacking project Design, manufacture and design of power management modules and system intelligent control modules, development of DC/DC and DC/AC inverter modules, and hardware and software design for system control; development of prototype for 3.5kW AC fuel cell backup power integrated power generation system 600 outages and a total of 3,100 hours of operation. Through the in-depth study of the reliability and durability of the fuel cell backup power system, and under the support of the research results of this project, the related technical level of the improved 5kW (-48V) DC fuel cell backup power supply has reached the international advanced level and is fuel Battery backup power systems provide core technical support in the communications industry. The expert group unanimously believed that the project had completed the research content stipulated in the project notice, basically reached the assessment index, and agreed that the project passed the acceptance.
