System and method of inspecting an air compressor for a fuel cell

Abstract

A system and a method of inspecting an air compressor for a fuel cell are proposed. The inspection system includes a fuel cell; an air compressor provided on an inlet side of a cathode of the fuel cell and provided with a motor; and a controller configured to calculate an estimated consumption current of the air-compressor motor through a relationship between an applied voltage and a rotation speed of the air-compressor motor and configured to compare the calculated estimated consumption current with a measured actual consumption current to determine whether a permanent magnet of the air-compressor motor is demagnetized.

Dependencies are inferred from the claim text.
