'''Aluminiumhydrid''' är en förening mellan [[aluminium]] och [[väte]] (kemisk formel AlH<sub>3</sub>) och är ett starkt [[Redox|reduktionsmedel]].<br />
<br />
==Framställning==<br />
Aluminiumhydrid framställs genom att tillföra [[aluminiumklorid]] till en lösning av [[litiumaluminiumhydrid]] i [[eter (kemikalie)|eter]]. Biprodukten [[litiumklorid]] fälls ut och aluminiumhydrid löst i eter kvarstår.<br />
:<math>\rm 3\ LiAlH_4(eter) + AlCl_3(s) \rightarrow 4\ AlH_3(eter) + 3\ LiCl(s)</math><br />
<br />
==Användning==<br />
Aluminiumhydrid används för att lagra och generera [[Väte#Gasformigt_väte|vätgas]] för vätgasdrivna fordon. Föreningen innehåller 10 viktprocent väte och kan lagra upp till 148 gram väte per liter, vilket är dubbelt så mycket som [[Väte#Flytande väte|flytande väte]].<br />
<br />
Vatten eller syrgas (luft) används för att frigöra vätet.<br />
:<math>\rm 2\ AlH_3 + 3\ H_2O \rightarrow Al_2O_3 + 6\ H_2</math><br />
:<math>\rm 4\ AlH_3 + 3\ O_2 \rightarrow 2\ Al_2O_3 + 6\ H_2</math><br />
