Abstract

UN PROCESO ELECTROQUIMICO PARA EL ALMACENAMIENTO DE ENERGIA Y LA GENERACION DE POTENCIA QUE CONSTA DE UNA SOLA CELULA O DE UN SISTEMA DE CELULAS UNITARIAS (10), EN DONDE CADA CELULA CONTIENE DE UN ELECTRODO A +VE (12) Y UN ELECTRODO A -VE Y UNA MEMBRANA EN CADA CELULA QUE LA DIVIDE EN UNA CAMARA +VE Y UNA -VE (22C Y 24C) PARA SOLUCIONES DE POSILITA Y ANOLITA (22, 24) A LAS QUE SE HACE RECIRCULAR A TRAVES DE UNAS BOMBAS SEPARADAS (26, 28) Y UNOS DEPOSITOS DE ALMACENAMIENTO (32, 34) Y DE VUELTA A LAS CAMARAS. SE UTILIZA UN PAR DE HIERRO Y AZUFRE, EN DONDE LA REACCION GENERAL ES: 2FE3+ + S2- = 2FE2+ + S(EQ-8), EN DONDE LOS IONES DE FE3+ SE PRESENTAN COMO LAS SALES DE CLORURO, BROMURO O YODURO Y EL SULFURO SE PRESENTA COMO LAS SALES DE SODIO, POTASIO, LITIO O AMONIO. LA CAMARA +VE CONTIENE UNA SAL IONICA SOLUBLE QUE ACTUA COMO UN PORTADOR DE CARGA DURANTE EL ALMACENAMIENTO DE ENERGIA, PREFERENTEMENTE CLORURO SODICO O POTASICO. HAY UNOS ELEMENTOS PARA COMPENSAR EL PH DEL SISTEMA Y HAY TAMBIEN UNOS ELEMENTOS PARA UNA TERCERA CAMARA (23C) PARA QUE EL SISTEMA SE PUEDA RECARGAR ELECTRICAMENTE DE FORMA MAS EFECTIVA.
