Conversión y Almacenamiento de Energía

ALMACENAMIENTO DE ENERGIA POR HIDROGENO Y ELECTROCATALISIS

  Se estudia el almacenamiento de hidrógeno en aleaciones metálicas formadoras de hidruros, para ser utilizado como vector energético en nuevas tecnologías no contaminantes. Se diseñarán y caracterizarán aleaciones novedosas, capaces de almacenar grandes cantidades de hidrógeno en fase gaseosa, y posibles de ser empleadas en la preparación de electrodos negativos para baterías alcalinas recargables. Se estudian los aspectos básicos relacionados con el proceso de intercalación de hidrógeno. Se elaboran modelos fisicoquímicos para caracterizar el comportamiento de los electrodos durante los procesos carga-descarga.
Ciclado de electrodos y baterías de litio de alta capacidad de carga. Optimización de técnicas de obtención de electrodos. Elaboración de un modelo fisicoquímico que permita explicar el comportamiento electroquímico de electrodos con materiales de inserción para electrodos de níquel y litio. Diseño, construcción y evaluación del comportamiento en operación de una celda prototipo de níquel/hidruro.
