摘要: A monitoring device (130) tracks a plurality of related metrics (122), each related metric (122) configured to monitor the same characteristic (121) of a fuel cell system (110) based on different types of data (312). The related metrics (122) may include a first metric (122A) derived from direct measurements of the characteristic (121) and a second metric (122B). The second metric (122B) may be inferred from indirect measurements of the characteristic (121). An analysis module (140) 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 (122). 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 (342) trained to identify related metrics (122) that are indicative of anomalous operation of the fuel cell system (110), such as operation under fuel leak conditions.

摘要: A mobile energy supply system may include a fuel source, an energy converter, and a transfer device. The fuel source may be disposed onboard a vehicle chassis and may hold a supply of a fuel. The energy converter may be disposed onboard the vehicle chassis and may convert at least a portion of the supply of the fuel from the fuel source into electric energy. The transfer device may be disposed onboard the vehicle chassis and be electrically couplable to a propulsion vehicle. The transfer device may transfer the electric energy from the energy converter offboard of the vehicle chassis and to the propulsion vehicle for powering a propulsion system of the propulsion vehicle.
