Fuel cell hybrid range-extender vehicle sizing: Parametric power optimization

E-transportation is a next generation technology for internal combustion engine phase-out. In present study, three drivetrain cases are designed: internal combustion engine (ICE), engine-fuel cell coupled configuration, and ICE-catalyst modes. First, the ICE-FC configuration is analyzed and compared with the ICE driven powertrain. Then, the emission of ICE-catalyst mode is compared with that of ICE-FC configuration. The proposed driveline parameters have been examined to monitor the emission, fuel economy, and efficiency of the overall hybrid system. The results indicated that in the new European driving cycle (NEDC), the mileage in hybrid mode has been extended from 3.4 km to 11.0 km. The results also show that by shifting from ICE alone to ICE-FC mode, the fuel consumption (gasoline) decreased from 26.241/100 km to 5.38 1/100 km. In addition, the NOx, CO, and HC species have been dropped by 47.7%, 61.7%, and 26.7%, respectively. The engine displacement, cell number of FC and GDL thickness are changed in two levels. Accordingly, when the GDL is thinner, the H-2 consumption is marginally lower while the FC energy output increases up to 5400 kJ and the electric fuel economy is promoted by 6.43%.
