Abstract
Ensamblaje de membrana-electrodo que consiste en una membrana de intercambio catiónico que contiene flúor (hecha de copolímero hidrolizado de tetrafluoroetileno con éter vinílico que contiene perfluorosulfuro con un PE = 900-1300) y capas de material electrodo porosas (hechas de electrocatalizador), material inactivo electrocondutor y aglutinante fluoropolimérico situado sobre ambas superficies de la membrana de intercambio catiónico. La membrana de intercambio catiónico que contiene flúor está hecha de copolímero hidrolizado de tetrafluoroetileno con éter vinílico que contiene perflorosulfuro, que tiene un grado de cristalinidad de 2-8 %, obteniéndose unas capas de material del electrodo porosas que tienen una porosidad entre 40 y 70 %, que disminuye en la dirección de la superficie de la membrana de intercambio catiónico con un gradiente de porosidad de 5-15 % por 1 µ. Dicho ensamblaje membrana-electrodo es utilizado en células combustibles, en electrolizadores de agua y en otros procedimientos electroquímicos.
