Abstract

CéLULAS DE COMBUSTìVEL DE óXIDO SóLIDO TUBULARES Uma pilha de célula de combustível tubular suportada em anodo inclui estruturas de interconexão que são resistentes à oxidação à alta temperatura, flexíveis para a acomodação de tensão por expansão térmica e para a provisão de um contato elétrico forte, têm baixa resistência elétrica e são baratas e de peso leve. As estruturas de interconexão podem ser formadas a partir de uma folha de metal, o que provê uma homogeneidade térmica melhorada por toda a pilha de célula de combustível, por causa da alta condutividade térmica do metal. As estruturas de interconexão são conformadas, adicionalmente, para a provisão de resiliência ou recursos tipo de mola para se permitir um movimento entre as células tubulares. Assim, um bom contato elétrico, uma liberação de tensão térmica e uma absorção de choque são simultaneamente obtidos.
