The widespread deployment of charging stations for HFVs, i.e. hydrogen fueling stations (HFSs), over the transportation infrastructure is fundamental to the hydrogen economy [ 3 ]. Meanwhile, photovoltaic (PV) power generation becomes one of the major renewable power sources in the modern power industry [ 4 ].
