Abstract
A quality evaluating apparatus has an inspection table for placing a first or second metal separator, and a light-permeable plate for applying a predetermined pressure to a ridge of the first or second metal separator to deform the ridge and allowing a deformed state of the ridge to be inspected through the light-permeable plate while the predetermined pressure is being applied to the ridge. The quality evaluating apparatus also has an image capturing mechanism for capturing an image of the deformed state of the elastic member through the light-permeable plate, and a comparing mechanism for comparing the captured image with a preset image to evaluate the quality of the ridge.
