The fuel cell electric vehicles: The highlight review

Transportation sector is the important sector and consumed the most fossil fuel in the world. Since COVID-19 started in 2019, this sector had become the world connector because every country relies on logistics. The transportation sector does not only deal with the human transportation but also relates to logistics. Research in every country has searched for alternative transportation to replace internal combustion engines using fossil fuel, one of the most prominent choices is fuel cells. Fuel cells can use hydrogen as fuel. Hydrogen can be fed to the fuel cells to provide electric power to drive vehicles, no greenhouse gas emission and no direct combustion required. The fuel cells have been developed widely as the 21st century energy-conservation devices for mobile, stationary, and especially vehi-cles. The fuel cell electric vehicles using hydrogen as fuel were also called hydrogen fuel cell vehicles or hydrogen electric vehicles. The fuel cells were misconceived by several people that they were batteries, but the fuel cells could provide electric power continuously if their fuel was provided continuously. The batteries could provide electric power as their only capacities, when all ions are released, no power could be provided. Because the fuel cell vehicles play important roles for our future transportation, the overall review for these vehicles is significantly interesting. This overall review can provide general and technical information, variety of readers; vehicle users, manufacturers, and scientists, can perceive and understand the fuel cell vehicles within this review. The readers can realize how important the fuel cell technologies are and support research around the world to drive the fuel cell vehicles to be the leading vehicles in our sustainable developing world.(c) 2022 Hydrogen Energy Publications LLC.

Automated summary

The transportation sector plays an important role in the consumption of fossil fuels worldwide. Since the start of the COVID-19 pandemic in 2019, it has become a crucial connector between countries due to the reliance on logistics. Researchers around the world are exploring alternative transportation options, and fuel cells, particularly those using hydrogen as fuel, have emerged as a prominent choice. Fuel cell electric vehicles have the potential to revolutionize the transportation sector by providing continuous electric power without greenhouse gas emissions. An overall review of fuel cell vehicles is of significant interest as it can provide valuable information for various stakeholders and promote the development of sustainable transportation.
