Abstract

Patente de Invenção: <B>"ELETRODOS DE DIFUSãO DE GáS PARA CéLULA DE COMBUSTìVEL DE MEMBRANA POLIMéRICA"<D>. A presente invenção descreve um eletrodo aperfeiçoado adequado para aplicação em células de combustível de electrólito de polímero sólido, o qual compreende um substrato condutor fino, poroso e planar que tem um lado revestido com uma pré-camada que consiste em carbono condutor que tem uma pequena área superficial misturada a um primeiro agente hidrofóbico, à qual é aplicada uma camada catal;itica que consiste em platina suportada sobre carbono condutor com uma grande área superficial, misturada a um segundo agente hidrofóbico. O grau hidrofóbico das camadas aplicadas é adequadamente ajustado para se obter a melhor exploração do catalisador e para aperfeiçoar o equilíbrio da água do processo.
