class fastga_he.models.propulsion.components.source.pemfc.components.perf_pemfc_efficiency.PerformancesPEMFCStackEfficiency(**kwargs)[source]

Bases: ExplicitComponent

Efficiency computation of the PEMFC with dividing the actual voltage provided by the fuel cell with the higher heating value (HHV) of hydrogen. The convertion into voltage form is simply calculated by dividing the HHV of hydrogen (285.5 kJ/mol) by the amount of electrons produced by single hydrogen particle and Faraday’s constant. source: https://www.nrel.gov/docs/fy10osti/47302.pdf

Store some bound methods so we can detect runtime overrides.

initialize()[source]

Perform any one-time initialization run at instantiation.

setup()[source]

Declare inputs and outputs.

Available attributes:

name pathname comm options

compute(inputs, outputs, discrete_inputs=None, discrete_outputs=None)[source]

Compute outputs given inputs. The model is assumed to be in an unscaled state.

An inherited component may choose to either override this function or to define a compute_primal function.

Parameters:

  • inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

  • outputs (Vector) – Unscaled, dimensional output variables read via outputs[key].

  • discrete_inputs (dict-like or None) – If not None, dict-like object containing discrete input values.

  • discrete_outputs (dict-like or None) – If not None, dict-like object containing discrete output values.
