Recuperación de agua del proceso electroquímico en la producción de Hidrogeno Verde.

Abstract

This study indicates a water recovery system from the electrochemical process in the production of green hydrogen, for which a prototype called a water recovery tank was manufactured, Additionally, they experimented with a prototype vehicle that runs on hydrogen batteries, powered by photovoltaic energy. For the analysis of the water recovery capacity of the electrochemical process, the prototype was placed in the water vapour outlet in the fuel cell experimenter of the Laboratory of Intelligent Networks and Renewable Energies of the Faculty of Sciences, the vehicle experiments were run at the same location. For the statistical analysis, a 2e2 factorial design was used in both cases, for the tank, the effect of the current through the load (1 A - 1.5 A) was factor A, and the purge time (every 10 min - every 25 min) was factor B, the variable studied was the amount of water recovered (ml - prototype). For the vehicle the variable was the operating time, factor A was the charging time of the solar panel and factor B was the radiation. Three replicates were made in each experiment, the average maximum value for the tank was 3.67 drops at the point (1.5 A, 10 min), in the case of the vehicle, the average maximum operating time is 162.37 s at the point (high radiation, 15 min). It is concluded that both the purge time and the current significantly affect the water recovery experiment, a total of 1.5ml of water was collected in two hours with an efficiency of 70%. In the case of the vehicle, the combined use of renewable energies was demonstrated. It is recommended to use special solenoid valves for hydrogen and avoid leaks during the process.
