Method and apparatus for fuel cell system fault detection

摘要

A method of detecting faults in a fuel cell system, the method comprising: comparing (110) a plurality of fuel cell measurements (105) to respective ones of a plurality of range limits to yield a plurality of range flags; differentiating (120) the fuel cell measurements (105) to yield a plurality of fuel cell rates; comparing (130) the fuel cell rates to respective ones of a plurality of rate limits to yield a plurality of rate flags; and classifying (140) the range flags and the rate flags to yield a fault detection decision.
