You will find  here the paper by Monica Burriel Abstract:
"An architectural design of the cathode microstructure based on combining electrostatic spray deposition (ESD) and screen-printing (SP) techniques has demonstrated to be an  innovative strategy to enhance the electrochemical properties of La2NiO4þd (LNO) as  oxygen electrode on Ce0.9Gd0.1O2ed (CGO) electrolyte for solid oxide fuel cells. For this purpose, the influence of the ESD process parameters on the microstructure has been systematically investigated. Electrochemical performances of four selected cathode microstructures are investigated: (i) 3-D coral nanocrystalline (average particle size ~ 100 nm) LNO film grown by ESD; (ii) 3-D coral nanocrystalline film (average particle size ~ 150 nm) grown by ESD with a continuous nanometric dense interface; (iii) porous screen-printed LNO film (average particle size ~ 400 nm); and (iv) 3-D coral nanocrystalline film (average particle size ~ 150 nm) with a continuous nanometric dense interface prepared by ESD topped by a LNO current collector  prepared by SP. A significant reduction in the polarization resistance (Rpol) is obtained (0.08 U cm2 at 700 C) for 3-D coral topped by the SP layer. Moreover LNO is found to be stable and compatible with CGO up to 800 C for only 10 days duration in air, making it potentially suitable for SOFCs cathode application."
