Table 5. Comparison results between the PV system and WT system powered the PEMEL.
Type/item | Rated Power | Efficiency system | The flow rate of hydrogen (mol/s) | The flow rate of hydrogen (Nm3/h) | Overall system efficiency [(PV or WT system) + (PEM-E130)] |
---|---|---|---|---|---|
PV system at (1000 W/m2 and 25°C) | 7000 | 16.63% | 7.517e-3 | 0.60655 | 5.43% |
WT system at (12 m/s and zero pitch angle) | 12300 | 57.07% | 8.073e-3 | 0.6514 | 18.77% |
