Abstract

FRITAS DE VEDAçãO DE BAIXO TEOR DE áLCALIS; E VEDAçõES E DISPOSITIVOS QUE UTILIZAM TAIS FRITAS. Trata-se de um dispositivo de pilha a combustível baseada em óxido sólido que incorpora um material de vedação resistente à permeação do gás hidrogénio a uma temperatura de vedação na faixa de temperatura intermediária de 600°C a 900°C, a vedação tendo um CTE na faixa de 100x 10^ -7^/°C a 120x10^ -7^/°C, em que o material de vedação consiste, em % de peso, de: (i) frita de vidro a 80% a 100% do peso, a própria frita de vidro tendo uma composição que inclui, em porcentagem molar, de: SiO~ 2~ a 15-65; Li~ 2~O a 0-5; Na~ 2~O a 0-5; K~ 2~0 a 0-10; MgO a 0-5; CaO a 0-32; Al~ 2~O~ 3~ a 0-10; B~2~O~ 3~ a 0-50; SrO a 0-25, em que a quantidade total de álcalis é menor do que 10 em % molar; e (ii) adição de zircónia ou leucita a 0% a 30% do peso.
