Abstract
A method of making a solid oxide fuel cell electrolyte includes preheating a substrate on which an oxide electrolyte layer is to be deposited to a substrate temperature of about 1100° C. and above, impinging a surface of a source comprising the oxide with an electron beam in an evacuated chamber at a pressure of about 10or less mm of Hg devoid of process gas, such as oxygen, to evaporate the oxide in the chamber, and placing the preheated substrate in the chamber where the oxide deposits on the preheated substrate. The oxide fuel cell electrolyte is deposited having a columnar oxide microstructure.
