Abstract
Systems and methods for detecting and validating a leak in a fuel cell system are presented. In certain embodiments, various fuel cell stack set points may be adjusted such that adequate Hflow data may be obtained to identify and validate an Hleak and/or a location of such a leak. In some embodiments, Hflow data may be obtained by adjusting certain fuel cell system operating parameters under a variety of operating conditions and/or modes and measuring flow data under such various operational conditions.
