Hydrogen production system through the electrolysis of water generated by photovoltaic solar energy.

Resumen de: MA62942A1

This invention constitutes, in itself, an innovative solution for the production of hydrogen based on the phenomenon of water electrolysis by a flat electrode electrolyzer. The electrical energy used comes from the conversion of solar energy into electricity using a photovoltaic system. The adaptation between the photovoltaic source and the electrolyzer is done by means of a device that does not exchange any energy with the PV-electrolyzer system. The proposed technique is based on the search for the optimal operating point by varying the distance between the two flat electrodes placed opposite each other by fixing one of the two plates (electrodes) and moving the other plate in translation. Indeed, a change in the inter-electrode distance causes a change in the volume of water between them; which subsequently influences the value of the connected load (electrolyzer). The moving plate approaches or moves away from the fixed electrode depending on the optimal operating point of the photovoltaic source. This movement is driven by the action of a stepper motor that transforms the rotational movement into a translational movement of the plate. This coupling, with a minimum of interfacing electronics, would lead to a substantial reduction in costs and thus improve the economic viability of hydrogen solar systems.
