Abstract:

Solid oxide fuel cells (SOFCs) can convert chemical energy into electric energy through the electrochemical reaction between hydrogen and oxygen, which is in line with the clean and low carbon orientation and is conducive to the realization of dual carbon target. Reducing the thickness of the electrolytes is beneficial for lowering the operating temperature of conventional SOFCs and improving their electrochemical performances in medium and low temperatures (< 600 ℃). The main process characteristics and research progress of several typical electrolyte preparation techniques are reviewed, and their advantages and limitations of electrolytes' industrial production are analysed.It is pointed out that physical vapor deposition represented by pulsed laser deposition and magnetron sputtering is more in line with the concept of clean production and more suitable for industrial production.

Key words: carbon neutrality, clean and low carbon, solid oxide fuel cell, electrolyte, thin film, medium and low temperature, physical vapor deposition, perovskite
