The invention relates to a fuel cell and cell hybrid energy management method. The method comprises the following steps that 1, a parameter identification module receives real-time voltage and current of a fuel cell and a cell; 2, a parameter identification module calculates open-circuit voltage and internal resistance of the fuel cell and the cell after identification in real time; 3, transmitting the real-time open-circuit voltage and internal resistance of the fuel cell and the battery to a model predictive control energy management module; and 4, taking the data obtained in the step 3 as parameters of a model predictive control energy management module, and finally calculating an output reference value of the fuel cell in the next step. According to the method, the used model parameters are adjusted in real time, and it is guaranteed that the system can achieve the optimization target under all operation conditions and under fuel cell and cell aging conditions.
