Stressed MSRI Anode (S1)


License Not Specified

Microstructure of an electrochemically aged active anode layer from a 25 mm anode-supported SOFC button cell produced by Materials and Systems Research, Inc (Salt Lake City, UT), characterized using xenon plasma FIB-SEM at Carnegie Mellon University on 30 October 2017.

The electrochemical aging procedure consisted of running the cell for 1,500 hours at 750°C, at a current density of 0.25 A/cm2, using wet (3% H2O) hydrogen as a fuel.

The microstructure is approximately 145x106x6 μm3; the voxel size in the dataset is 50x50x50 nm3. The phase IDs in the segmented data are as follows: 1:pore, 2:Ni, 3:Yttria-stabilized zirconia (YSZ). The greyscale values in the un-segmented data follow the same order, from darkest to brightest.
