class h2integrate.converters.hydrogen.h2_fuel_cell.LinearH2FuelCellPerformanceConfig(*, system_capacity_kw, fuel_cell_efficiency_hhv)#

Configuration class for the hydrogen fuel cell performance model.

Parameters:

  • system_capacity_kw (float)

  • fuel_cell_efficiency_hhv (float)

system_capacity_kw#

The capacity of the fuel cell system in kilowatts (kW).

Type:

float

fuel_cell_efficiency_hhv#

The higher heating value efficiency of the fuel cell (0 <= efficiency <= 1).

Type:

float

system_capacity_kw: float#
fuel_cell_efficiency_hhv: float#
class h2integrate.converters.hydrogen.h2_fuel_cell.LinearH2FuelCellPerformanceModel(**kwargs)#

Performance model for a hydrogen fuel cell.

The model implements the relationship: electricity_out = hydrogen_in * fuel_cell_efficiency_hhv * HHV_hydrogen

where: - hydrogen_in is the mass flow rate of hydrogen in kg/hr - fuel_cell_efficiency is the efficiency of the fuel cell (0 <= efficiency <= 1) - HHV_hydrogen is the higher heating value of hydrogen (approximately 142 MJ/kg)
