Title:
FUEL CELL STACK
Document Type and Number:
WIPO Patent Application WO/2017/006945
Kind Code:
A1
Abstract:
A fuel cell stack (10) comprising: six fuel cells (20) alternately laminated in a lamination direction; and seven collector members (30). Each of the six fuel cells (20) comprise a fuel electrode (21), an air electrode (23), and a solid electrolyte layer (22) arranged between the fuel electrode (21) and the air electrode (23) and having a zirconia-based material as the main component thereof. The six fuel cells (20) include first fuel cells (20A) positioned in the center in the lamination direction and second fuel cells (20B) positioned at one end in the lamination direction. The intensity ratio for tetragonal zirconia relative to cubic zirconia in a Raman spectrum of the solid electrolyte layer (22) for the first fuel cells (20A) is larger than the intensity ratio for tetragonal zirconia relative to cubic zirconia in a Raman spectrum of the solid electrolyte layer (22) for the second fuel cells (20B).
