Abstract

Patente de Invenção: <B>"CAMADA CATALìTICA PARA CéLULAS DE COMBUSTìVEL DE ELETRóLITO POLIMéRICO"<D>. A invenção refere-se a uma camada catalítica em um material de substrato que contém um polímero condutor de prótons (ionómero), partículas de carbono eletricamente condutoras e partículas finas de pelo menos um metal precioso. A camada catalítica é obtenível revestindo o material de substrato com uma tinta que contém uma dispersão de partículas de carbono e pelo menos um composto complexo de metal precioso orgânico em uma solução do ionómero e secando o revestimento abaixo de uma temperatura em que o ionómero ou o material de substrato é danificado termicamente, os metais preciosos nos compostos complexos estando presentes com um número de oxidação de 0 e os compostos complexos sendo decompostos termicamente durante secagem para formar as partículas de metais preciosos finas.
