Formation of thin-film ZrO2-Y2O3 electrolyte of solid oxide fuel cell by pulsed electron-beam treatment and magnetron sputtering method
Abstract
This paper reports results producing anode-supported YSZ electrolyte thin films by magnetron sputtering method for solid oxide fuel cell applications. Pulsed electron-beam treatment was used for preprocessing porous anode substrates for the purpose reducing their surface porosity. Microstructures of the anode substrates before and after electron-beam modification as well as samples with YSZ electrolyte films have been investigated. Current - voltage and powered characteristics of experimental fuel cell was measured.
