Abstract
A method of forming hydrogen by electrolysis in a cell containing a hydrohalic acid produced from a reaction process using carbon particles as an input energy source wherein the acid for electrolysis is produced by reacting the electrolysis separated halogen with water and carbon particles in a reaction area communicated with the electrolysis cell. The reaction can also be made in the presence of a catalyst.
