Abstract
A vehicle, a vehicle fuel reactant leak detection system, a computer program product, and a computer implemented method of detecting leakage of a fuel reactant from a vehicle. The vehicle includes one or more fuel cell modules, a fuel supply source to supply a fuel reactant to the one or more fuel cell modules via a high-pressure fuel supply line, a fuel supply valve configured to open and close fuel reactant flow through the high-pressure fuel supply line, and a computing device, operatively connected to the fuel supply source. The computing device includes one or more processors caused to conduct, in response to a detection as sensor data of pressure in the high-pressure fuel supply line when the vehicle engine is in a non-operating state, fuel pressure analysis of the sensor data, and detect, based on the fuel pressure analysis, leakage of the fuel reactant at the fuel supply valve.
