Use of a hydrogenated silicon to recover dihydrogen, which is useful in fuel cells

摘要

Use of a hydrogenated silicon to recover dihydrogen in a high yield, where the hydrogenated silicon is contacted with an alkaline solution, is claimed. Independent claims are included for: (1) a process for preparing dihydrogen comprising contacting a hydrogenated silicon with an alkaline solution to generate dihydrogen, and recovering and/or upgrading of dihydrogen thus formed; and (2) fuel cells comprising an anode operating in dihydrogen associated with a device for supplying of dihydrogen comprising hydrogenated silicon contacted with an alkaline solution generating the dihydrogen from hydrogenated silicon.
