Abstract
A solid oxide fuel cell (SOFC) article including a SOFC unit cell having a functional layer of an average thickness of not greater than about 100 μm, wherein the functional layer has a first type of porosity having a vertical orientation, and the first type of porosity has an aspect ratio of length:width, the width substantially aligned with a dimension of thickness of the functional layer.

-62. (canceled)
A solid oxide fuel cell (SOFC) article comprising:
- a SOFC unit cell comprising a functional layer having an average thickness of not greater than about 100 μm, wherein the functional layer comprises a first type of porosity having a vertical orientation, wherein the first type of porosity has an aspect ratio of length:width, the length substantially aligned with a dimension of thickness of the functional layer.
A solid oxide fuel cell (SOFC) article comprising:
- a SOFC unit cell comprising a functional layer having an average thickness of not greater than about 100 microns, wherein a portion of a porosity of the functional layer comprises:
- a first type of porosity having an aspect ratio of length:width of at least about 1.1:1 and a vertical orientation with respect to a horizontal axis defining a width of the functional layer;
- and
- a second type of porosity having a non-vertical orientation with respect to the horizontal axis of the functional layer.
1 more element
A method of forming a solid oxide fuel cell SOFC article, the method comprising:
- forming a green functional layer having a content of pore forming agents;
- and
- uniaxial hot pressing the green functional layer to form a finished functional layer under transformation conditions selected from the group of conditions consisting of temperature, pressure, time, and atmosphere, wherein a significant portion of pores formed from the pore forming agents vertically orient with respect to a horizontal axis during uniaxial hot pressing.
