Numerical analysis of 40 kW multistack fuel cell system featuring series-type active hydrogen recovery
MATLAB/Simulink simulations are performed to investigate and innovative the performance of a multistack fuel cell (MFC) system consisting of 1 ~ 4 10 kW fuel cells arranged in a series configuration. The system is equipped with a tail purge valve, fixed to vent impurities from the stack every 60 s, and an active hydrogen recovery system based on a mechanical compressor to recover the excess hydrogen from the exhaust stream and return it to the inlet side for re-use. The validity of the simulation model is confirmed by comparing the rated power output of the MFC system with that of a commercial fuel cell platform. The validated model is employed to evaluate the I-V response of the 10 kW, 20 kW, 30 kW and 40 kW MFC systems. The effects of the stack temperature on the output power are then investigated. It is shown that, for each MFC system, the maximum efficiency is obtained for stack temperatures in the range of 65–75 °C. Moreover, the system efficiency increases by approximately 7% as the cathode air pressure increases from 1.1 bar to 1.8 bar. Finally, the active hydrogen recovery ratios of the 20 kW, 30 kW and 40 kW MFC systems are found to be 14.1%, 11.8%, and 10.65%, respectively.
