Proton-exchange membrane fuel cell model

This power source model in FAST-OAD-CS23-HE represents a PEMFC stack that generates electric energy through a series of chemical reactions. The Hydrogen Oxidation Reaction (HOR) at the anode splits hydrogen gas (\(\text{H}_2\)) into protons (\(\text{H}^+\)) and electrons (\(\text{e}^-\)). Then the \(\text{H}^+\) ions disolve into the solution between the membrane, while the \(\text{e}^-\) travel through an external circuit, creating an electric current. At the cathode, the Oxygen Reduction Reaction (ORR) combines oxygen (\(\text{O}_2\)) with \(\text{H}^+\) and \(\text{e}^-\) to form water (\(\text{H}_2\text{O}\)).

\[\text{Anode (HOR):} \quad \text{H}_2 \rightarrow 2\text{H}^+ + 2e^-\]

\[\text{Cathode (ORR):} \quad \frac{1}{2} \text{O}_2 + 2\text{H}^+ + 2e^- \rightarrow \text{H}_2\text{O}\]

\[\text{Overall Reaction:} \quad \text{H}_2 + \frac{1}{2} \text{O}_2 \rightarrow \text{H}_2\text{O}\]

This component can be activated through the powertrain configuration file (PT file). The registered installation positions and polarization model option can be found in the description of the PEMFC stack position and model fidelity option in options.
