The PBC cube improves the cathode electrochemical performance, enhancing the power output and durability of the PCFC.

Caption

TME results show that the PBC particles are cubic and the {100} crystal planes are exposed on the surface. This gives rise to more surface oxygen vacancies and efficient Cu2+-O-Cu3+ electron-hopping transition paths, favoring high electrocatalytic activity with expeditious oxygen adsorption/activation, and facilitating the oxygen reduction reaction (ORR) process. The particle-cube PBC cathode assembled at 950 ℃ (PBC-950) exhibits significantly enhanced power density and excellent durability on PCFCs.
