Recent advancements in the automotive sector are steering the conversation towards more sustainable transportation solutions, particularly in the realm of hydrogen fuel cell technology. A study led by John Evans Dakurah from Gazi University, Turkey, has provided valuable insights into the performance of a 70 kW Proton Exchange Membrane (PEM) Fuel Cell Electric Bus (PEMFCEB) using MATLAB/Simulink for modeling and simulation.
As concerns about the environmental impacts of traditional Internal Combustion Engine Vehicles (ICEVs) grow, the demand for cleaner alternatives has surged. While lithium-ion battery electric vehicles (EVs) have gained popularity, they face limitations such as restricted range and lengthy charging times. In contrast, hydrogen fuel cell vehicles offer a compelling solution, boasting longer ranges, faster refueling, and zero emissions.
Dakurah’s research focuses on a PEM fuel cell electric bus equipped with a 50 kWh buffer battery and a total hydrogen capacity of 38 kg. The study integrates two hybrid energy management systems: fuzzy logic and a conventional on-off system. By simulating various driving cycles, including the New European Driving Cycle (NEDC) and the Worldwide Harmonized Light Vehicle Test Procedure (WLTP), the research evaluates key performance metrics such as range, hydrogen and oxygen consumption, and fuel cell efficiency.
The findings are significant. During the NEDC cycle, the bus achieved a total range of 492.02 km with the fuzzy logic system, outperforming the traditional on-off system, which managed 448.85 km. Similarly, under the WLTP cycle, the fuzzy logic approach yielded a range of 407.61 km compared to 362.33 km for the conventional system. “These results highlight the potential of advanced energy management systems in optimizing fuel cell performance,” Dakurah stated, emphasizing the importance of such innovations in the transition to sustainable transport.
The commercial implications of this research are substantial. As cities and countries push for greener transportation options, the development of hydrogen fuel cell vehicles could reshape the energy landscape. With their ability to deliver longer ranges and quick refueling times, PEM fuel cell buses could become a preferred choice for public transport systems, potentially leading to increased investments in hydrogen infrastructure.
Moreover, the integration of sophisticated energy management systems like fuzzy logic not only enhances vehicle efficiency but also opens up opportunities for manufacturers to differentiate their products in a competitive market. As the automotive industry continues to evolve, studies like Dakurah’s could play a crucial role in fostering innovation and driving the adoption of hydrogen vehicles.
This research was published in ‘Automotive Experiences,’ shedding light on the ongoing shift towards more sustainable transportation solutions and the role of hydrogen fuel cells in achieving this goal.
