Abstract

LA INVENCION SE REFIERE A UNA DISPOSICION PORTATIL DE CELULAS DE COMBUSTIBLE PARA CONVERTIR HIDROCARBUROS LIQUIDOS O GASEOSOS EN CORRIENTE ELECTRICA CONTINUA, COMPRENDIENDO DICHA DISPOSICION UNAS CELULAS DE COMBUSTIBLE EN FORMA DE DISCO QUE SE COLOCAN AXIALMENTE EN CAPAS, FORMANDO UNA PILA, QUE VA FIJADA POR UN TIRANTE, TENIENDO LA CELULA DE COMBUSTIBLE UNA ABERTURA (3) PARA LA ADMISION DE UN PRIMER GAS Y PARA ALOJAR EL TIRANTE. LA DISPOSICION DE CELULAS DE COMBUSTIBLE SE CARACTERIZA PORQUE LA CELULA COMPRENDE: UN ELECTROLITO CONDUCTOR DE IONES (17), EN FORMA DE ELECTROLITO DE CERAMICA PARA TEMPERATURAS ELEVADAS O ELECTROLITO POLIMERICO PARA TEMPERATURAS BAJAS; UNA CAPA DE CATODO POROSO (18) COMO ELECTRODO DE OXIGENO Y UNA CAPA DE ANODO POROSO (19) COMO ELECTRODO DEL COMBUSTIBLE, UNA A CADA LADO DEL ELECTROLITO (17); UN SOPORTE (2) PERMEABLE A LOS GASES QUE TIENE UNA PRIMERA Y UNA SEGUNDA SUPERFICIE, Y CONDUCTOS PARA EL PASO DE GASES; UNA PEQUEÑA PLACA SEPARADORA (20) DE LA QUE AL MENOS UNAPARTE SE APOYA SOBRE LA PRIMERA SUPERFICIE DEL SOPORTE (2) Y UNA GRAN PLACA SEPARADORA ELECTRICAMENTE CONDUCTORA (1) QUE SE APOYA EN LA SEGUNDA SUPERFICIE DEL SOPORTE (2) Y COMPRENDE MEDIOS QUE GUIAN LOS GASES DE MANERA DETERMINADA, Y COOPERAN CON LOS CONDUCTOS DEL SOPORTE (2). LA GRAN PLACA SEPARADORA (1) PUEDE INCLUIR MEDIOS (7, 8, 9, 15) PARA LA GUIA DETERMINADA DE GASES, EXTENDIENDOSE CONVENIENTEMENTE DICHOS MEDIOS A LO LARGO DE LINEAS CONSTANTES QUE NO ESTAN RAMIFICADAS, DESVIANDOSE TANTO DE LA DIRECCION RADIAL COMO DE LA TANGENCIAL, Y DESCRIBIENDOSE POR LA FORMULA [1] PH = (MAS MENOS) A [(R/R SUB,O ) 2 A1] 0,5 A-B ARCTAN [(R/R O ) 2 A-1] .
