Abstract

The high volatility of boron from borosilicate glass sealants often leads to boron deposition and poisoning of La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) cathode, presenting a challenge for the development of reliable solid oxide fuel cells (SOFCs). In this paper, we report that boron volatilization from borosilicate glass at 700
