**3. Results**

Each RTO strategy has been analyzed using the FCHPS diagram shown in Figure 1 and control loops setting listed in Table 1.

The hydrogen consumption during a load cycle is evaluated for each RTOk strategy (k = 1 ÷ 7) using the performance indicator *FuelT* = *FuelFr*(*t*)*dt* (measured in liter [L]) and the fuel economy compared to sFF strategy, Δ*FuelTk* = *FuelTk* − *FuelT*0, is listed in Tables 2–4.


**Table 2.** Fuel economy for *kfuel* = 0 and different *Pload*.


**Table 3.** Fuel economy for *kfuel* = 25 and different *Pload*.

**Table 4.** Fuel economy for *kfuel* = 50 and different *Pload*.
