Charge separation and transport in La0.6Sr0.4Co0.2Fe0.8O3-δ and ion-doping ceria heterostructure material for new generation fuel cell

The charge separation processes, from nano-particle level to the device level, are key to the scientific understanding of the SIFCs. The synergistic effect of junction and energy band alignment towards the charge separation from particle to device level, in particular blocking electron crossover, as well as the promotion of ion transport by built-in field, contribute to the working principle and facilitates high power output in the SIFC. Thus, it can realize fuel cell functions and fuel-to-electricity conversion through different means from the conventional fuel cell, wherein the semiconductor-ionic heterostructure, charge separation and junction play key roles, and joining physics and electrochemical processes are in force.127
