Extended Data Fig. 4: TEM image and EDS mapping of PCFC (Cell 3) after 8,000 h operation on methanol.

From: Highly durable, coking and sulfur tolerant, fuel-flexible protonic ceramic fuel cells

Extended Data Fig. 4

a, TEM image of lamella from BZY20 PCFC electrolyte/cathode interface prepared by FIB. bh, HAADF image of the electrolyte/cathode interface, and corresponding EDS maps of Ba, Zr, Y, Co, Fe and O. There is no chemical reaction between the electrolyte and electrolyte which indicates the excellent chemical compatibility of cathode with electrolyte. EDS mapping of cathode shows there is no obvious elemental segregation.
