Abstract

EL CAMPO DE FLUJO REACTIVO EN EL LADO DEL CATODO DE UN MONTAJE DE CELULA DE COMBUSTIBLE SE FORMA DE UNA LAMINA HECHA DE PARTICULAS DE CARBONO QUE SE UNEN JUNTAS POR UN ENLACE DE POLIMERO DE FLUORCARBONO. EL CAMPO DE FLUJO REACTIVO DE CATODO ES NO POROSO, Y ES HIDROFOBO DEBIDO A LA PRESENCIA DEL ENLACE DE POLIMERO. LAS PARTICULAS DE CARBONO SON PREFERIBLEMENTE LAMINILLAS DE CARBONO QUE SON EMPAQUETADAS JUNTAS MUY FUERTEMENTE, Y QUE SOLO REQUIERE UNA CANTIDAD PEQUEÑA DE ENLACE DE POLIMERO PARA FORMAR UNA LAMINA SOLIDA. LA LAMINA SUMINISTRARA CANALES DE FLUJO REACTIVO DEL CATODO, CONDUCIRA ELECTRONES Y CALOR Y MINIMIZARA LA ABSORCION DE ACIDO EN UNA PILA DE CELULAS DE COMBUSTIBLE DEBIDO A SU NATURALEZA HIDROFOBA.
