Abstract
Disclosed herein are an electrode with a three-dimensional structure comprising two or more layers of nanowire array layer in which first and second nanowires of different materials, and imaginary third nanowires composed of air, are arranged side by side, in which nanowires in one layer are crossed by nanowires in an adjacent layer, a method of manufacturing the electrode, an anode for a solid oxide fuel cell having the structure described above, and a solid oxide fuel cell including the anode.
Claims21
An electrode with a three-dimensional structure comprising two or more layers of nanowire array layer in which first and second nanowires of different materials, and imaginary third nanowires composed of air, are arranged side by side,
- wherein nanowires in one layer are crossed by nanowires in an adjacent layer.
A method of manufacturing an electrode comprising:
- preparing a patterned substrate having a shape arranged with rectangular columns lying side by side;
- depositing a first material while tilting the patterned substrate at an inclined angle of 60° to 85° and depositing the first material on one edge of convex columns;
- depositing a second material by rotating the patterned substrate on which the first material is deposited by an angle of 180° and depositing the second material on the other edge of the convex columns;
- and
- attaching a flat plate to a portion on which the first material and the second material are deposited, and removing the patterned substrate to obtain a nanowire array layer in which the first nanowire composed of a first material, the second nanowire composed of a second material, and the imaginary third nanowire composed of air are arranged side by side.
