Abstract

L'invention concerne un matériau de stockage d'hydrogène permettant de stocker de l'hydrogène par adsorption et, plus particulièrement, un matériau de stockage d'hydrogène permettant de stocker et d'utiliser l'hydrogène dans un état proche de la température ambiante et de la pression atmosphérique et également d'augmenter de manière radicale la capacité de stockage de l'hydrogène. Selon l'invention, le matériau de stockage d'hydrogène est prévu de telle sorte qu'un métal de transition léger, tel que le titane (Ti), est appliqué sur deux sites centraux d'une structure hexagonale polymère, notamment, un polyphénol, un polyaniline ou un polyparaphénylène; ou qu'un métal de transition léger, tel que le titane (Ti) ou le scandium (Sc) est substitué par un atome d'hydrogène (H) d'une structure de transpoly-acétylène; ou qu'un métal de transition léger, tel que le titane (Ti) ou le scandium (Sc) est appliqué sur deux sites d'une chaîne de carbone de cis-acétylène ou de transpoly-acétylène. De ce fait, un grand nombre de molécules d'hydrogène peuvent être adsorbées sur un atome métallique à stocker de manière stable.
