Abstract

SE UTILIZA UN CUERPO EN FORMA DE PANAL CONDUCTOR ELECTRICO, PREFERIBLEMENTE EXPRIMIDO DE UNA LECHADA DE POLVO DE METAL, PARA HACER UN CALENTADOR DE RESISTENCIA MEDIANTE EL SUMINISTRO DE LUGARES DE ELECTRODO (11). DICHO CALENTADOR PUEDE POR EJ, EMPLAZARSE CORRIENTE ARRIBA DE UN CONVERTIDOR CATALITICO INCLUYENDO UN CATALIZADOR PRINCIPAL O UN CONVERTIDOR CATALITICO PUEDE INCLUIR LOS ELECTRODOS (11) PARA DARLE ENERGIA, EN ADICION A PORTADOR CATALIZADOR EN SU ESTRUCTURA DE PANAL. EL CUERPO DE PANAL ESTA FORMADO CON NO UNIFORMIDADES ESTRUCTURALES PRE-DETERMINADAS, PARA ASI INFLUENCIAR SUS CARACTERISTICAS DE RESISTENCIA ENTRE LOS ELECTRODOS (11). LAS NO UNIFORMIDADES PUEDEN SER RANURAS (12) CORTADAS EN EL CUERPO. OTROS EJEMPLOS INCLUYEN VARIACIONES DE GROSOR DE LAS PAREDES DE LAS CELDAS A TRAVES DEL CUERPO, VARIACIONES DE LA LONGITUD DE LAS PAREDES AXIALES DE LAS CELDAS SOBRE EL CUERPO, E INTERRUPCION DE PAREDES DE CELDAS AISLADAS EN POSICIONES PREDETERMINADAS.
