We investigated hybrid fuel cell-battery configurations that overcome thermal management issues in fuel cell powertrains for heavy-duty Class 8 trucks. The battery is sized so that it has sufficient capacity to provide supplemental power and energy on a hill climb transient at end-of-life. A dynamic load sharing strategy is developed to distribute the power demand between the fuel cell system (FCS) and the energy storage system in a manner that optimizes their lifetimes. The FCS end-of-life is identified as the terminal point beyond which the stack cannot generate the rated power with target power density at 0.7 V and 40°C ambient temperature. Reaching the target lifetime with a-Pt/C cathode catalyst in one hybrid configuration requires voltage clipping to 813 mV, idle power limited to 50 kW, catalyst overloading to 0.45 mg/cm2 total Pt in anode and cathode, and 44% active membrane area oversizing. The stack and FCS drive cycle efficiencies decrease by 4.2 % and 5.4%, respectively, during the electrode lifetime. The FCS performance, durability and cost are compared with the targets of 68% peak efficiency, 0.30 mg/cm2 total Pt loading, 2.5 kW/gPGM Pt group metal (PGM) loading, 750 mW/cm2 power density, 25,000-h lifetime and $80/kW cost.

One potential solution for reducing carbon dioxide emissions from ships and meeting the Energy Efficiency Existing Ship Index (EEXI) requirements is to use a hybrid propulsion system that combines liquid hydrogen and liquefied natural gas fuels. To improve energy efficiency for diesel-electric dual-fuel ship propulsion systems, an engine power limitation system can also be used. This paper examines the potential use of these systems with regard to several factors, including compliance with EEXI standards set by the International Maritime Organization, fuel ratio optimisation, installation requirements, and economic feasibility. As a case study, an LNG carrier is analysed, with dual-fuel diesel-electric and two hybrid systems adjusted to meet IMO-EEXI requirements with engine power limitation percentages of 25%, 0% (hybrid option 1), and 15% (hybrid option 2), respectively. From an economic standpoint, the liquid hydrogen-based system has competitive costs compared to the dual-fuel diesel-electric system, with costs of 2.1 and 2.5 dollars per kilogram for hybrid system options 1 and 2, respectively.

“…[26][27][28][29][30] In particular, EIS is a widespread tool to monitor degradation in PEM fuel cells [31][32][33] and is also applied in FCEVs for on-road state-of-health monitoring. 34,35 Applying EIS at low hydrogen partial pressure (hpp) might provide valuable insights while mitigating safety and cost concerns. However, since the cathode side in a PEM fuel cell is usually rate-determining, few studies investigate the impact of reduced hpp on the fuel cell performance.…”
