SYSTEMS AND METHODS FOR VALIDATING DETECTED LEAKS IN FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for detecting and validating a leak in a fuel cell system.SOLUTION: 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.SELECTED DRAWING: Figure 1
