Abstract

Patente de Invenção: <B>"ESTRUTURA DE ELETRODO POROSA PARA UM SENSOR DE GáS E DISPOSIçãO DE SENSOR"<D>. A invenção refere-se a uma estrutura de eletrodo porosa para um sensor de gás, bem como a uma disposição de sensor. A invenção tem por base a tarefa de pór à disposição uma estrutura de eletrodo, bem como uma disposição de sensor, para detecção de hidrocarbonetos em um gás de medição, que, além de uma baixa impedância, garante uma alta estabilidade no tempo e reprodutibilidade do sinal de medição. A tarefa é solucionada por uma estrutura de eletrodo porosa, que apresenta uma armação de ouro condutora, que contém componentes oxídicos.
