Title:
The fuel cell cassette and fuel cell stack for solid oxide form fuel cells
Document Type and Number:
Japanese Patent JP6039110
Kind Code:
B2
Abstract:
Provided is a fuel cell cassette capable of assuredly suppressing separator deformation and maintaining good battery characteristics. A fuel cell cassette (2) includes a flat plate-shaped single cell (11), a separator (12), a fuel electrode frame, an interconnector and an air electrode insulating frame (15) stacked together. In the fuel cell cassette (2), the separator (12) and the fuel electrode frame (13) are joined by welding. The air electrode insulating frame (15) has gas channels (75, 76) defined therein for flow of oxidant gas. The fuel cell cassette has a welding mark (77) formed on an exposed region of the separator (12) inside the gas channel (75, 76) such that the exposed region of the separator (12) is fixed to the fuel electrode frame by the welding mark (77).
