Introduction: A hydrogen fuel cell operates through a process known as electrochemical conversion, converting hydrogen and oxygen into electricity and water. The key steps involved in the operation of a hydrogen fuel cell are as follows:
Hydrogen Input (Anode): Hydrogen gas (H2) is introduced into the fuel cell at the anode. At the anode, a catalyst facilitates the splitting of hydrogen molecules into protons (H+) and electrons (e-).
Electron Flow (External Circuit): The generated electrons flow through an external circuit, creating an electric current. This flow of electrons constitutes the electrical output of the fuel cell.
Proton Movement (Through Membrane): Simultaneously, protons move through a proton exchange membrane (PEM) or another type of electrolyte to reach the cathode. The membrane only allows the passage of protons, ensuring the separation of electrons and protons.
Cathode Reaction: At the cathode, the electrons, protons, and oxygen from the air combine. The cathode typically contains another catalyst to facilitate the reaction. The combination of electrons, protons, and oxygen results in the formation of water (H2O).
The overall chemical reaction in a hydrogen fuel cell can be represented as:
2H2 + O2 --> 2H2O + electricity
The electricity generated during this process can be utilized to power electric motors, providing a clean and efficient source of energy. One of the significant advantages of hydrogen fuel cells is that the only byproduct of the reaction is water, making them a promising and environmentally friendly technology for various applications, including transportation and stationary power generation.
Regulations about emissions from on-highway trucks are becoming more stringent across major global markets. In Europe, starting from 2030, manufacturers will be mandated to achieve a 30 percent reduction in CO2 emissions for new on-highway trucks compared to 2019 levels. Simultaneously, the United States has set an ambitious emissions-reduction target, aiming for a 46 percent reduction by 2027 compared to 2010 levels. Furthermore, fifteen U.S. states, spearheaded by California, have implemented additional mandates stipulating that by 2030, 30 percent of trucks sold must be zero-emission vehicles. Chinese regulators are also actively involved in emissions reduction efforts, requiring Original Equipment Manufacturers (OEMs) to achieve a 24 percent reduction in emissions for heavy-duty trucks from 2021 compared to 2012 levels. Given China's recent commitment to achieving net-zero emissions by or before 2060, additional, more ambitious long-term targets for emissions reduction in the heavy-duty truck sector are anticipated. These regulatory initiatives reflect a global commitment to addressing climate change by reducing emissions from the transportation sector, particularly from on-highway trucks. As the automotive industry faces increasing pressure to adopt sustainable practices, manufacturers are compelled to innovate and invest in cleaner technologies to meet these stringent emission targets and contribute to a more environmentally friendly future.
