Abstract
El proceso de descarbonización se ha vuelto fundamental debido al cambio climático y sus consecuencias. Es aquí donde el hidrógeno verde (H2V) ha tomado un rol importante como combustible verde. El presente trabajo busca mejorar un reactor de water-splitting para generación de H2V, el cual cuenta con un primer prototipo validad experimental y numéricamente. Se prueba el segundo prototipo utilizando los mismos parámetros de operación del primero, con el fin de validarlo tanto numéricamente con un modelo matemático que describe el proceso, como con resultados experimentales. La temperatura alcanzada mejora aproximadamente en 200 K, y la producción de H2V en más de 5 mol. La eficiencia energética aumenta de un 0,028% a un 3,02% y la eficiencia de conversión de un 0,9% a un 1,1%. A lo largo del documento se presentan las características distintivas del nuevo prototipo, y la lógica de su aplicación.

The present work aims to improve a watersplitting reactor for H2V generation, which has a first prototype experimentally and numerically validated. The second prototype is tested using the same operating parameters of the first one, to validate it both numerically with a mathematical model that describes the process, and with experimental results. The temperature reached improves by approximately 200 K, and the H2V production by more than 5 mol. The energy efficiency increases from 0.028% to 3.02% and the conversion efficiency from 0.9% to 1.1%. The distinctive features of the new prototype, and the rationale for its application, are presented throughout the paper.
