In view of the increasing energy requirements of the economy and the growing world population, alternatives to fossil fuels are crucial for reducing CO2 and pollutant emissions. The use of hydrogen as an energy source and the use of fuel cells, for example for the operation of vehicles, can help with the desired decarbonization and thus make an important contribution to environmental protection.
This article from the publication series Transport and Environment explains the physical and chemical principles of fuel cell technology and shows why hydrogen may have a bright future as a clean energy source.
The “Transport and the Environment” publication series takes an interdisciplinary and in-depth look at the topics of transport and the environment. The articles focus on pollution and its consequences, as well as current challenges and trends with regard to environmentally friendly alternative drive systems.
The series serves to share knowledge and provide expert support for current discourse. The articles are published several times a year at irregular intervals and are available to download free of charge as PDF files.
