DURABILITY EVALUATION METHOD, DURABILITY EVALUATION EQUIPMENT, AND DURABILITY EVALUATION PROGRAM FOR UNIT CELL, AND UNIT CELL FOR FUEL CELL

摘要

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).
