Abstract

"PROCESSO PARA PREPARAçãO DE UM ELETRODO DE DIFUSãO GASOSA". A presente invenção refere-se a um processo para preparação de um eletrodo de difusão gasosa, particularmente para a eletrólise de uma solução aquosa de ácido clorídrico, sendo que em uma primeira etapa a) uma dispersão de um catalisador contendo metais nobres e de um ionómero condutor de prótons em um solvente inerte é pulverizada em um veículo eletricamente condutivo eventualmente provido de uma massa de revestimento contendo uma mistura de fuligem de acetileno - politetrafluoretileno e em uma segunda etapa b) o solvente orgânico é retirado.
