Title:
METHOD FOR EVALUATING DURABILITY OF UNIT CELL, DEVICE FOR EVALUATING DURABILITY, PROGRAM FOR EVALUATING DURABILITY, AND UNIT CELL OF FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2008/029954
Kind Code:
A1
Abstract:
A method for evaluating, in an information processor, durability of the unit cell
of a fuel cell that comprises a polymer electrolytic membrane, two planar electrodes
provided on the opposite sides of the polymer electrolytic membrane, two planar
separators in each of which a groovelike gas channel for supplying gas to the electrode
is formed, and a material for sealing the side face of the electrode, the method
comprising a reception step (S01), model creation steps (S02, S03), a moisture
distribution calculation step (S04), a strain/stress calculation step (S05),
a equivalent stress calculation step (S06), evaluation value derivation steps
(S07, S08), and an output step (S09).
