Hybrid Fuel Cars. A car that uses two or more distinct power sources as fuels is a hybrid car. The common type of hybrid car is one with a combination of internal combustion engine and electric motors. Hybrid cars may use a combination of various power sources like gasoline, hydrogen, compressed air, solar, wind and waste heat.

A device and method for predicting the remaining life of a hybrid fuel cell based on a nonlinear observer.
The purpose of this invention is to provide a device and method for predicting the remaining life of a hybrid fuel cell based on a nonlinear observer, belonging to the field of marine hybrid power. The fuel cell remaining life prediction method of this invention includes the following steps: S1: The marine hybrid power system composed of a fuel cell and a battery adopts a fully active control architecture. The fuel cell and its converter adopt power closed-loop control, and the battery and its converter adopt voltage-current dual closed-loop control; S2: Collect the fuel cell output current and bus voltage; S3: Design a nonlinear observer to estimate the fuel cell degradation factor; S4: Calculate the remaining life based on the relationship between the fuel cell degradation factor and the remaining life; S5: Calculate the maximum output current of the fuel cell based on the fuel cell degradation factor and transmit it as a control constraint to the fuel cell controller. This invention does not require additional sensors, the algorithm is simple to implement and highly versatile, and it is of great significance for the control and monitoring of hybrid power systems.
