DIFFUSION LAYER SEPARATOR JUNCTION, ITS MANUFACTURING METHOD, FUEL CELL AND FUEL CELL STACK

摘要

PROBLEM TO BE SOLVED: To downsize and save weight of a diffusion layer separator junction and improve conductivity.

SOLUTION: The diffusion layer separator junction 7 is provided with diffusion layers 3, 4 for diffusing and supplying fuel or an oxidant to electrodes of a unit cell 1, and metal separators 5, 6 fitted in the vicinity of the diffusion layers 3, 4 for separating the fuel and the oxidant. The diffusion layers 3, 4 and the separators 5, 6 are integrated by a laser welding.
