The use of road transport in human life has become an integral part of social development. Vehicles are the main consumers of energy and one of the main sources of air pollution.The urgent solution of socially important problems of environmental protection and conservation of natural resources necessitates the transition to alternative environmentally friendly energy and highly efficient technologies for its implementation in transport. A special place among alternative energy carriers in the global research practice is given to hydrogen.The global concept of hydrogen energy originated in the mid-1970s as a natural reaction of the scientific community to the growing problem of declining global hydrocarbon energy reserves. Today, the threat of a rapidly growing
