Title:
FUEL CELL STACK
Document Type and Number:
Japanese Patent JP2018133240
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell stack by which the occurrence of a problem, such as a crack or fracture, owing to injection molding and press shaping can be prevented.SOLUTION: A fuel cell stack comprises a stack of single cells, each including: a membrane-electrode assembly including an electrolyte membrane, an anode electrode disposed on one side of the electrolyte membrane and a cathode electrode disposed on the other side of the electrolyte membrane; an anode-side separator disposed on one side of the membrane-electrode assembly for shutting off a fuel gas; and a cathode-side separator disposed on the other side of the membrane-electrode assembly for shutting off an oxidizing gas. The anode-side separator and the cathode-side separator are each composed of a flat plate-like body. Further, each single cell has a fin between the anode-side and cathode-side separators for isolating the anode-side and cathode-side separators from each other and partitioning off a coolant flow path between the anode-side and cathode-side separators.SELECTED DRAWING: Figure 2
