Slurry-coated cermet anode

Fig. 28 Two-dimensional schematic of the microstructure of a slurry-coated cermet anode.

Furthermore, slurry-coated cermet anodes have various long-term stability problems, particularly due to the fine particle size of the metallic component.It has also been reported that the tolerance for impurities in fuels is very limited. High levels (100 ppm) of H S may cause significant irreversible performance loss due to anode poisoning.
