| titleOfInvention | Process for the production of hydrogen |
| abstract | The invention relates to a process for production of hydrogen of high purity by photoelectrochemical means with low energy consumption. The process is carried out in an electrochemical cell which comprises at least one anodic chamber with an anode and at least one cathodic chamber with a cathode, in which the two chambers are separated by an ion-exchange membrane, where: i) said anodic chamber contains an aqueous anodic solution which comprises the Fe2+ ion, and said aqueous solution is adjusted to a pH less than or equal to 5; ii) a sacrificial substance is added to said anodic chamber; iii) said anodic solution is irradiated with ultraviolet light and/or visible light; iv) said cathodic chamber contains an aqueous cathodic solution which has a proton concentration equal to or higher than 10-3 M; and v) electric current is fed between said anodic chamber and said cathodic chamber separated by said membrane, this membrane being a proton-selective ion- exchange membrane impermeable to the iron and impermeable to the sacrificial substance. |
