Abstract
A method for simultaneous co-generation of electric energy and hydrogen by totally electrochemical means which includes an electricity storage phase by electrolysis of an electrolysable metal solution and formation of a hydrogen-electrolysable metal battery cell and, an electricity recovery and hydrogen generation phase by operation of said battery cell. The electrolysable metal is chosen from zinc, nickel and manganese.
Claims15
A method for simultaneous co-generation of electric energy and hydrogen comprising:
- providing a solution of an electrolysable metal choosen from Zn, Ni and Mn, a first electrode and a second electrode,
- electrolysing the solution so as to:
- deposit the electrolysable metal on the first electrode,
- generate aqueous hydrogen in the solution at the second electrode,
- and form a hydrogen-electrolysable metal cell,
- operating the hydrogen-electrolysable metal cell so as to simultaneously:
- produce gaseous hydrogen from the aqueous hydrogen at the second electrode,
- oxidize the electrolysable metal from the first electrode,
- and generate electric energy between the first and the second electrodes.
