Solid oxide fuel cell (SOFC) has been recognized as one of promising energy conversion devices. However, the durability of SOFC at an operating condition is one of major huddles for commercialization. Specifically, volatile Cr species can be generated from metallic components in SOFC, such as interconnects and gas supply tubes. These Cr species can poison and react at the active sites of the cathode, causing a rapid degradation of cell performance. Also, many studies have been shown that the improvement of electrochemical performance can be achieved by infiltration and it can reduce long-term degradation. Our research group developed an open-source simulation code, ERMINE, based on a finite element framework. In ERMINE, species transport, the oxidation reduction reaction (ORR), and Cr poisoning are simulated based on given operational conditions. Thus, the effect of infiltrates on Cr-poisoning in SOFC cathode will be presented through microstructurally resolved HPC simulations of electrochemistry.
