Abstract:

In order to improve the hydrogen utilization rate of fuel cell engines， a fuel cell anode loop model was developed based on the AMESim platform,and completed model integration and calibration. Based on practical engineering experience, a new purging strategy that correlates anode loop temperature, pressure and reaction current was proposed. Using the anode loop model of the fuel cell engine, the parameter optimization boundary was calculated, and the optimization and fitting of the purge control parameters was completed. According to the simulation results， compared with the original purge strategy， the new strategy can make the hydrogen consumption rate decrease from 0.866 kg to 0.8 kg per 100 km under NEDC cyclic condition， and the theoretical economy can be improved by 7.5%. Then the new strategy was verified on a fuel cell vehicle， and the hydrogen consumption rate is 0.81 kg per 100 km， which is basically consistent with the simulation results. The driving range of the vehicle is increased from 484 km to 510 km， by 5.4%. And the effectiveness of model-based purge strategy optimization scheme is verified.
