Abstract

PROCESSO DE OBTENçãO DE SUSPENSõES AQUOSAS PARA ELETRODOS DE PILHAS A COMBUSTìVEL DE óXIDO SóLIDO E OUTROS DISPOSITIVOS ELETROCATALìTICOS. A inovação ora proposta descreve um processo para obtenção de suspensões aquosas preferenciais para a obtenção de (nano) compósitos casca-caroço de polímeros hidrofílicos e sua aplicação na obtenção de suspensões de alto teor de sólidos geradoras de eletrodos para dispositivos eletrocatalíticos de estado sólido (como pilhas a combustível de óxido sólido, reatores de membrana de óxido e outros dispositivos eletrocatalíticos) e/ou eletrodos superficialmente modificados, através da inserção de íons metálicos na água de hidratação destes (nano) compósitos no passo prévio ao processamento cerâmico (queima e sinterização).
