Abstract

Composiciones electroquimicas y termicas de aleacion para almacenamiento de hidrogeno que proporcionan un desempeno superior, que incluye una aleacion para almacenamiento de hidrogeno electroquimica que proporciona caracteristicas superiores de descarga a baja temperatura. Las composiciones de la aleacion incluyen microestructuras en la region de interfase que son altamente porosas y que incluyen particulas metalicas cataliticas. Las microestructuras incluyen una fraccion de volumen grande de espacios vacios que tienen formas esfericas o en forma de canal y que estan estructuralmente lo suficientemente abiertas para facilitar una mayor movilidad de las especies reactivas dentro de la microestructura y en la cercania de las particulas metalicas cataliticas. Por consiguiente, los resultados tienen una mayor accesibilidad a los sitios reactivos. La mayor movilidad de las especies reactivas y/o la mayor densidad de las particulas cataliticas conducen hacia una cinetica mas rapida y un desempeno mejorado (por ejemplo una potencia mas alta), especialmente en temperaturas de operacion bajas. Las microestructuras pueden formarse a traves de la inclusion de un elemento de calibracion de la microestructura en la composicion de la aleacion, a traves del control de las condiciones del procesamiento y/o a traves de la inclusion de etapas de grabado al agua fuerte en el procesamiento de pos-formacion de las aleaciones de almacenamiento de hidrogeno.
