Abstract :

In this study, the possibility of using mica for this application was investigated. First, mica gasket includingsmall Phlogopite flakes with organic binders was used and its performance duringas leakage was simulated in asmall set-up simulating fuel cell operating condition (air atmosphere, temperature of 800 °C and time of 100 h).Due to heating of mica during operation, binders were burned out and remaining pores acted as leakage path.These leakage paths were filled by acid boric and the mica performance was enhanced up to 20%. The majorleakage path (mica and its adjacent interface) was filled by a glass and a successful application of mica-glasslayer was obtained for leakage prevention.
