Abstract
A monitoring device tracks a plurality of related metrics, each related metric configured to monitor the same characteristic of a fuel cell system based on different types of data. The related metrics may include a first metric derived from direct measurements of the characteristics and a second metric. The second metric may be inferred from indirect measurements of the characteristic. An analysis module may detect a potential fuel leak based, at least in part, on an error, difference, deviation, and/or other comparative analysis of the related metrics. Alternatively, or in addition, potential fuel leaks may be detected by use of an artificial intelligence, machine learned and/or machine learning (AI/ML) model trained to identify related metrics that are indicative of anomalous operation of the fuel cell system, such as operation under fuel leak conditions.
