Abstract

EN PILAS ELECTROQUIMICAS PRIMARIAS O RECARGABLES, SE PUEDE DESPRENDERHIDROGENO. LA INVENCION ESTA RELACIONADA CON EL USO DE UN MATERIAL DE ELECTRODO AUXILIAR QUE COMPRENDE DIOXIDO DE MANGANESO Y UN CATALIZADOR, EN CALIDAD DEL OXIDANTE, QUE PREVE LA RECOMBINACION DE HIDROGENO A PRESION, POR EJEMPLO, ESTANDO EL HIDROGENO A UNA PRESION QUE VARIA ENTRE, SUBSTANCIALMENTE, UNA PRESION MANOMETRICA DE CERO Y LA PRESION DE DESCARGA DE LA PILA. SE TRATA DE UNA PILA SELLADA QUE TIENE UN CATODO DE DIOXIDO DE MANGANESO, UN ANODO DE ZINC Y UN ELECTROLITO ACUOSO QUE HACE CONTACTO TANTO CON EL CATODO COMO CON EL ANODO. EL ELECTROLITO ACUOSO PUEDE SER ALCALINO O PUEDE SER CLORURO DE AMONIO O CLORURO DE ZINC O SUS MEZCLAS. EL MATERIAL DE ELECTRODO AUXILIAR, QUE PUEDE MEZCLARSE CON EL MATERIAL DEL CATODO O FORMARSE EN UN ELECTRODO AUXILIAR DISCONTINUO, PUEDE COMPRENDER OPCIONALMENTE UN SUBSTRATO POROSO Y, EN CUALQUIER CASO, COMPRENDE MNO2 Y UN CATALIZADOR PARA LA RECOMBINACION DEL HIDROGENO A PRESION CON EL MNO2. EL SUBSTRATO PUEDE SER NEGRO DE CARBON O GRAFITO; EL CATALIZADOR PUEDE SER UN METAL, UNA SAL METALICA O UN OXIDO METALICO DE ELEMENTOS TALES COMO EL PLOMO, EL NIQUEL, EL TITANIO, EL LANTANIO, EL CROMO, EL VANADIO, EL TANTALO Y SUS ALEACIONES CATALITICAMENTE ACTIVAS. MAS CONCRETAMENTE, EL CATALIZADOR PUEDE SER PLATA, PLATINO, OXIDO DE PLATA O DIOXIDO DE PLATA.
