Abstract

SE PRESENTAN UNA SERIE DE ELECTROLITOS DE ACIDO FOSFORICO MODIFICADOS QUE CONTIENEN COMPUESTOS DE CARBONO FLUORINADO Y FLUIDOS DE SILICONA COMO ADITIVOS. LOS ELECTROLITOS MODIFICADOS PUEDEN MEJORAR EL RENDIMIENTO DE LA PILA DEBIDO A LA CINETICA MEJORADA DE REDUCCION DEL OXIGENO. ESTOS ADITIVOS, PREFERIBLEMENTE, SON PERFLUOROEXANOSULFONATO DE POTASIO (C6F12HO3S), NONAFLUOROBUTANOSULFONATO DE POTASIO (C4F9HO3S), PERFLUOROTRIBUTILAMINO [(C4F9)3N] Y POLIMETILSILOXANO [(SI(CH3)2O-)N] LOS ADITIVOS SE AÑADEN EN UNA CANTIDAD DE ENTRE EL 1 Y 5% CON RESPECTO AL ELECTROLITO DE ACIDO FORFORICO.
