In a method of monitoring a fuel cell unit, at least one pair of measured values, including a measured current value and a measured voltage value (I, U) are determined at the outputs of the fuel cell unit. The measured voltage value (U) is compared with a limit value (P), which is a function of the measured current value (I) by way of a limit characteristic polarization curve. It is concluded that the condition of the fuel cell unit is faulty when the measured voltage value (U) or a function of the measured voltage value is smaller than or equal to a predefined threshold value.

Method of monitoring a fuel cell unit

A method and system for an improved vehicle monitoring system in order to provide a cost-effective and scalable system design for industrial application through the use of machine learning and data mining technologies on data acquired from a plurality of vehicles to create models. Frequent acquisition of vehicle sensor and diagnostic data enables comparison with the created models to provide continuing analysis of the vehicle with respect to repair, maintenance and diagnostics.
