Abstract
Official abstract text for this publication.
A solid oxide fuel cell is disclosed herein. The fuel cell includes a silicon substrate, an electrolyte film laminated on the silicon substrate, and a gas flow path formed inside the silicon substrate. The electrolyte film is opposed to the gas flow path via an electrode film. A portion of a side wall of the gas flow path has a fillet shape, and the portion is close to the electrolyte film.
First claim
Opening claim text (preview).
What is claimed is: 1 . A solid oxide fuel cell comprising: a silicon substrate; an electrolyte film laminated on the silicon substrate; and a gas flow path formed inside the silicon substrate, wherein the electrolyte film is opposed to the gas flow path via an electrode film, and wherein a portion of a side wall of the gas flow path has a fillet shape, and the portion is close to the electrolyte film. 2 . The fuel cell according to claim 1 , wherein in a plan view of the silicon substrate, the portion of the side wall of the gas flow path having the fillet shape extends over an entire circumference of the gas flow path. 3 . The fuel cell according to claim 1 , wherein an inclination angle of the side wall of the gas flow path with respect to the electrolyte film is substantially 90 degrees at a position apart from the electrolyte film. 4 . The fuel cell according to claim 3 , wherein an inclination angle of the portion of the side wall of the gas flow path having the fillet shape with respect to the electrolyte film gradually changes. 5 . The fuel cell according to claim 4 , wherein a radius of curvature of the portion of the side wail of the gas flow path having the fillet shape is within a range of 1 μm to 10 μm. 6 . The fuel cell according to claim 3 , wherein an inclination angle of the portion of the side wall of the gas flow path having the fillet shape with respect to the electrolyte film is substantially 55 degrees.
