Abstract
The present invention relates to a method for manufacturing hydrogen by an improved electrolytic process; to electrolytic cells (electrolyzers) adapted to such a process and to devices comprising such electrolytic cells. The invention further relates to new uses of aqueous hydrazine; particularly as an electrolyte.
Claims12
An electrolytic process for manufacturing hydrogen from water, said process comprising the step of electrolysing a composition comprising water, hydrazine and potassium hydroxide wherein
- said composition comprises 0.5-5 wt. % hydrazine;
- said composition comprises up to 10 wt. % potassium hydroxide;
- a voltage of 12-240 V is applied to said composition;
- and
- cathode material and anode material being selected from titanium and its alloys or plated with titanium and its alloys.
