Abstract

EN UNA CELDA DE ZINC ALCALINA SE HA PREVISTO PARA EVITAR UNA ACUMULACION DE GAS DE HIDROGENO, QUE SE GENERA A TRAVES DE LA CORROSION DEL ZINC DEL ANODO, UNA IMPULSION EN FORMA DE TOQUES DE UN ANILLO DE CATODO CON UN MEDIO DE ADHERENCIA VISCOSO, QUE ESTA MEZCLADO CATALITICAMENTE CON UN METAL ACTIVO (P.EJ. RANEYNI). EL HIDROGENO ORIGINADO SEGUN EL CONTACTO CONDUCTOR ELECTRONICO HACIA EL CATODO EN UN CATALIZADOR APOYADO SOBRE POTENCIAL ALTAMENTE POSITIVO SE ABSORBE Y SE RECOMBINA CON ALTO GRADO DE TRANSFORMACION PARA CONSEGUIR AGUA. LA APLICACION DE MEDIOS ADHERENTES QUE CONTIENEN CATALIZADOR, CON PREFERENCIA UN PEGAMENTO ACTIVO, SOBRE EL CUERPO DEL CATODO O SOBRE UN COMPONENTE DE CELDA QUE SE ENCUENTRA EN CONTACTO SUPERFICIAL (SEPARADOR RECIPIENTE DE LA CARCASA) PUEDE CONSEGUIRSE POR MEDIO DE PINCEL, A TRAVES DE LA INYECCION A PARTIR DE UNA PUNTA O A TRAVES DE PUNZONES.
