[:en]Hydrogen as an inexhaustible source of energy and its use as a clean fuel, the last decades have created the concept of the hydrogen economy, in which most invests Germany. In fact, that country is getting a lot of energy from renewable sources, which leads to the problem of storage. Hydrogen as a renewable energy source, which are a by-product water and heat is a great link to renewable energy as a tank.<\/p>\n
Technologies based on hydrogen use other developed countries such as France, the Scandinavian countries, Italy, Iceland, the US, Canada and Japan. It is the Japanese car manufacturer Toyota launched the first car on hydrogen, which\u00a0 young assistant professor with the Faculty of Mechanical Engineering and Naval Architecture in Zagreb Ankica \u0110uki\u0107 served as a prototype for the development of the first Croatian bike on hydrogen. During the preparation of the doctoral dissertation on the subject of hydrogen fuel cells, the idea emerged to produce hydrogen bicycles. It is the electric bicycle which electric motor uses electricity from hydrogen fuel cells, and a device that produces electricity without harmful emissions. Price of its prototype amounted to 100,000 kuna, but with its commercialization the price could be half as much. There is an investor interest in this invention, but has not yet been fully realized. Scientists believe that this is the first step in the production of hydrogen vehicles which follow the production of motor bicycles and later the first Croatian car on hydrogen.[:hr]Vodik kao neiscrpan izvor energije te njegovo kori\u0161tenje kao \u010disto gorivo, zadnjih su desetlje\u0107a stvorile pojam vodikova ekonomija, u koju najvi\u0161e ula\u017ee Njema\u010dka. Naime, ondje se dobiva puno energije iz obnovljivih izvora \u0161to dovodi do problema pohrane. Vodik kao obnovljiv izvor energije, \u010diji su nusprodukt voda i toplina je izvrstan link prema obnovljivim izvorima kao spremnik energije.<\/p>\n
Tehnologije zasnovane na vodiku razvijaju i druge zemljepoput Francuske, skandinavskih zemalja, Italije, Islanda, SAD-a, Kanade i Japana. Upravo je japanski proizvo\u0111a\u010d automobila Toyota lansirao prvi automobil na vodik koji je mladoj znanstvenici, docentici sa Fakulteta strojarstva i brodogradnje u Zagrebu Ankici \u0110uki\u0107, poslu\u017eio kao prototip za izradu prvog hrvatskog bicikla na vodik. Tijekom izrade doktorske disertacije ne temu vodikovih gorivih \u010dlanaka, javila se ideja za izradu bicikla. Radi se o elektri\u010dnom biciklu koji za pogon elektromotora koristi elektri\u010dnu energiju iz vodikovih gorivih \u010dlanaka, odnosno o ure\u0111aju koji proizvodi elektri\u010dnu energiju bez \u0161tetnih emisija. Cijena njezinog prototipa iznosila je 100.000 kuna, a uz komercijalizaciju cijena bi mu mogla biti upola ni\u017ea. Interes investitora za ovaj izum postoji, no jo\u0161 nije u potpunosti realiziran. Znanstvenica vjeruje kako je ovo prvi korak proizvodnje vozila na vodikov pogon kojem slijedi proizvodnja bicikla a kasnije i prvog hrvatskog automobila na vodik.[:de]Wasserstoff als eine unersch\u00f6pfliche Energiequelle und seine Verwendung als ein sauberes Brennstoff haben in dem letzten Jahrzehnt das Konzept der Wasserstoffwirtschaft, in die Deutschland am meisten investiert, geschaffen.
