The paper proposes a method for producing nanostructured solid oxide fuel cells by liquid injection plasma spraying. Two different methods of creating nanostructured functional layers by plasma deposition are discussed. First, in suspension plasma spraying (SPS), nanopowders are introduced into the plasma in a solvent. The second method is represented by solution precursor plasma spraying (SPPS), which injects liquid precursors directly into the plasma flame. The issues of differences in the microstructure of cross sections and SEM images obtained by different coating methods are considered. The advantages of the SPPS method for obtaining coatings with high stoichiometric flexibility and high porosity are indicated. The advantages of SPS methods for obtaining dense layers that are most suitable for thin electrolytes are indicated. The paper investigates the effect of using different injection methods from suspensions or liquid precursors on the pulse of the injected droplets, and considers how differences in the pulse of the injected droplets affect the deposition efficiency. It is pointed out that both methods have a huge potential for application in the production of high-performance SOFCs. The issues of control and management of the technical process of forming SOFCs layers by liquid injection plasma spraying are considered. |
