Abstract

"MéTODO PARA A FORMAçãO DE UM CONJUNTO DE ELETRODOS DE MEMBRANA, MéTODO PARA A FORMAçãO DE UMA MEMBRANA REVESTIDA COM CATALISADOR E CONJUNTO DE ELETRODOS DE MEMBRANA". Trata-se de uma aplicação eletroquímica que utiliza fluoropolímeros amorfos que apresentam um conjunto de eletrodos de membrana, o qual é durável e uniforme, e possui uma boa integridade estrutural, produzido por meio de um método que evita uma sinterização longa e complicada dos fluoropolímeros incorporados a temperaturas elevadas indesejáveis.
