Title:
FUEL BATTERY CELL STACK, FUEL CELL MODULE, POWER GENERATION SYSTEM, AND METHOD FOR MANUFACTURING FUEL BATTERY CELL STACK
Document Type and Number:
Japanese Patent JP2020140856
Kind Code:
A
Abstract:
To suppress a dense membrane such as a solid electrolyte membrane from being damaged in a short time by improving the oxidation resistance (robustness) of a fuel battery cell, even in an emergency stop in which current is cut off and fuel supply is stopped, and the like.SOLUTION: A fuel battery cell stack according to an embodiment includes: a substrate: a plurality of fuel battery cells each of which includes a fuel side electrode, a solid electrolyte membrane and an oxygen side electrode stacked therein in order from a substrate side on the substrate; an interconnector membrane electrically connecting between the fuel side electrode and the oxygen side electrode of the fuel battery cells adjacent to each other among the plurality of fuel battery cells; and a porous ceramic membrane covering at least the interconnector membrane in a region between the fuel side electrodes of the fuel battery cells adjacent to each other.SELECTED DRAWING: Figure 1
