vodíkového

Vodíkového is the genitive singular form of the Czech adjective vodíkový, meaning "hydrogen-" or "of hydrogen." It is used to express relation to hydrogen in noun phrases, especially in technical and scientific contexts. For example, vodíkového paliva means "of hydrogen fuel," and vodíkové články refers to hydrogen fuel cells. The form is chosen to agree with the gender, number, and case of the noun it modifies.

Etymology and formation: the adjective vodíkový is derived from the noun vodík (hydrogen) with the common Czech suffix -ový to form a descriptive adjective. The genitive singular vodíkového appears when the governing noun is in genitive or in contexts requiring that form, such as vodíkového paliva ("of hydrogen fuel"). The term has been part of Czech scientific vocabulary since the 19th century, paralleling the broader international adoption of hydrogen terminology.

Usage in terminology: vodíkového occurs in phrases describing properties, materials, or concepts related to hydrogen. Common examples include vodíkové palivo (hydrogen fuel), vodíkové články (hydrogen fuel cells), vodíkové hospodářství (hydrogen economy), and vodíkové vazby (hydrogen bonds). It also appears in broader fields such as vodíková energetika (hydrogen energy) and vodíkové technologie (hydrogen technologies). The word is integrated into standard Czech scientific and engineering prose, serving as a concise way to denote hydrogen-related qualification.
