VEHICLE FUEL CELL SENSOR PLAUSIBILITY CHECK

A vehicle fuel cell system assembly (1) comprising - a first fuel cell system (100) comprising a first sensor (110) and a first control unit (120) adapted to control the first fuel cell system (100) based on a value of the first sensor (110), - a second fuel cell system (200) comprising a second sensor (210) and a second control unit (220) adapted to control the second fuel cell system (200) based on a value of the second sensor (210), and - a common supply (50) of coolant, air or fuel to the first and second fuel cell systems (100, 200), wherein the vehicle fuel cell system assembly (1) is configured to perform a sensor plausibility check of the first sensor (110) and the second sensor (210) and use a value of a sensor (110, 210) that has passed the plausibility check instead of a value of a sensor (110, 210) that has not passed the plausibility check.
