Popis: To further promote fuel cell applications, the Tsinghua fuel cell team has developed a metallic bipolar plates fuel cell system. This paper first introduces the overall structure and working principle of the metallic bipolar plates fuel cell system. Secondly, the steady-state characteristics of fuel cell are introduced: 1) The mass of FC stack is 140kg. 2) The rated output power and peak output power of the stack are 96.2kW and 106.1kW respectively. 3) The rated output power and peak output power of the FC system are 81.3kW and 88.0kW respectively. The volumetric power density of the FC stack developed by Tsinghua team is 3.3 kW /L. Finally, the dynamic characteristics of fuel cell system are introduced: 1) The control error of current and anode inlet pressure is less than 3%. 2) The control error of cathode inlet pressure is less than 5%. 3) In most cases, the control error of air mass flow if less than 10%. The experiment results show that the metallic bipolar plates fuel cell system developed by the Tsinghua fuel cell team can stably output 81.3kW power, with the highest efficiency up to 53.2% and good dynamic characteristics, which can be further applied to actual vehicles.
