Structural differences between electrolyte-layer free fuel cell and conventional solid oxide fuel cell

This work explains the strategies for better understanding of the difference between conventional solid oxide fuel cell (SOFC) and electrolyte-layer free fuel cell (EFFC). Based on the devices performance conditions, it can be explained how both of the technologies are working in the same way while the internal mechanisms could be different. Mainly, this work will show the structural differences between the two devices.
