The invention discloses an intelligent control method of a hydrogen fuel cell based on a fixed time extremum search algorithm. The method comprises the following steps: firstly, acquiring the real-time output power of the hydrogen fuel cell; after the real-time output power of the hydrogen fuel cell is processed by the inside of the hydrogen fuel cell controller, a current set value of the hydrogen fuel cell is output; and finally, according to the current set value of the hydrogen fuel cell, adjusting the actual output current of the hydrogen fuel cell, after the actual output current of the hydrogen fuel cell is equal to the current set value, continuing to repeat the steps, and controlling the hydrogen fuel cell to track the maximum power value within the adjustment time. Compared with the prior art, the method does not depend on a hydrogen fuel cell system model, can enable the hydrogen fuel cell to complete maximum power tracking within the adjustment time, can carry out strict convergence proving and stability analysis, and has good robustness and reliability.
