Abstract	A new mechanism is suggested to explain the physical phenomenon of the appearance of additional new emission components of hydrogen lines in the spectra of active galactic nuclei (AGNs). The mechanism is based on the assumption that a dense clump of hydrogen is ejected from an AGN and expands rapidly due to a presumed explosion. Two main features of this phenomenon are explained fairly simply: a) the pronounced shift of the additional components from the main components (up to several thousand kilometers per second); b) the large width of the additional components, reaching 100–200 Å. The large share of emission by the additional components in comparison with the main lines is also explained well. Estimates obtained for the physical parameters of the new formations in AGNs fit well into modern concepts of AGNs and the forms of their activity.
