Resumen

La producción limpia de energías alternativas, es un reto que afronta la sociedad, por ello, a través del análisis y diseño realizado a un prototipo de celda de producción de hidrógeno tipo protónico a nivel de planta piloto (PEM), operando en condiciones potenciostáticas de 1 V, 1,23 V, y 5 V y condiciones galvanostáticas de 30 mA, 40 mA, 50 mA, 70 mA, 80 mA y 90 mA durante 10 minutos, utilizando como catalizador KOH y cuatro electrodos de acero previamente activados con una separación de 3 mm entre ellos (superficie 73 cm2), se permitió obtener los parámetros termodinámicos como son la entalpia de la reacción, la Energía Libre de Gibbs, y la Entropía; además se estableció el potencial de trabajo experimental óptimo y la eficiencia energética cuando se utilizaba una membrana Nafion
117 activada (superficie 36 Cm2) y en ausencia de la misma.
