This work extends the literature with an extensive experimental validation of a predictive EMS that exploits route-based long-term predictions in the form of optimized reference trajectories for the battery state of charge. The experimental validation is performed with a real passenger fuel cell vehicle and strongly focuses on the real-world application where random influences such as traffic cause considerable disturbances with respect to the long-term prediction. The validation comprises two stages: First, real driving tests are repeatedly conducted on public roads, analyzing the robustness of the predictive EMS and assessing fuel efficiency gains over a nonpredictive EMS. Second, chassis dynamometer tests are performed where a selected real driving cycle is reproduced to compare the two EMSs directly.

In this parallel liquid supply system, the distribution of electrolyte flow is closely related to the flow resistance in each branch. During operation, gas bubbles generated by chemical and physical processes tend to accumulate in the electrode pores, obstructing electrolyte flow and leading to uneven electrolyte distribution. Previous studies have mainly focused on single-cell experiments using constant flow pumps, which differ significantly from the nearly constant pressure difference liquid supply within the stack electrodes. To investigate the effects of gas evolution on liquid flow under constant pressure difference conditions, we propose a gravity-driven electrolyte feeding system for testing in a single cell, which simulates the flow conditions encountered in real stack applications. Under the interaction between gas bubbles and liquid flow, hydrogen evolution reactions at the scale of “mA cm<sup>-2</sup>” significantly reduce the electrolyte flow through the porous electrode. When the pressure difference drops below a critical threshold, the electrolyte flow rate continues to decrease significantly and may even stop entirely.
