Abstract

UN ELEMENTO DE UN ACUMULADOR CON ELECTRODO POSITIVO (1) Y ELECTRODO NEGATIVO (2) CONTIENE COMO SEPARADOR UNA MEMBRANA SINTETICA (3) MICROPOROSA, DE REDUCIDA PERMEABILIDAD Y UN ELECTRODO AUXILIAR (4) PARA EL CONSUMO DE OXIGENO, EN CORTOCIRCUITO ELECTRICO CON EL ELECTRODO NEGATIVO, QUE DEBIDO A SU DISPOSICION EN LA PARTE POSTERIOR DEL ELECTRODO NEGATIVO, ES DIRECTAMENTE ACCESIBLE PARA EL OXIGENO PRODUCIDO EN EL ELECTRODO POSITIVO. LOS POROS DEL SEPARADOR PRESENTAN UN DIAMETRO DE PORO MEDIO MAS PEQUEÑO QUE EL DE LOS POROS DE LOS ELECTRODOS, QUE PERMANECE TAMBIEN PEQUEÑO, SI A LO LARGO DE LA DURACION DEL CICLO, AUMENTA LA POROSIDAD DE LOS ELECTRODOS COMO CONSECUENCIA DEL HINCHAMIENTO O DE LA CORROSION INTERNA, PREFERENTEMENTE EN LA MICROZONA. EL SEPARADOR MANTIENE CONSECUENTEMENTE SU GRAN AFINIDAD ELECTROLITICA, QUE LE PROTEGE DE UNA DESECACION PREMATURA, UN MOTIVO DE FALLO HABITUAL EN PILAS DE BOTON ALCALINAS.
