The invention provides a parameter matching method and device for a fuel cell hybrid power system. The method comprises the following steps: determining a parameter matching joint feasible region of the fuel cell hybrid power system; an alternative parameter combination meeting the actual working condition of the rail transit vehicle is screened out from the parameter matching joint feasible region, and a preliminary parameter matching discrete alternative scheme set is obtained; building a multi-objective optimization function by taking the whole life cycle cost, the service time, the power system specific power and the specific energy under the vehicle operation condition as optimization objectives; and by adopting a swarm intelligent optimization algorithm, determining an optimal distribution result based on a parameter combination in the initial parameter matching discrete alternative scheme set and load distribution when the multi-objective optimization function takes a minimum value, and further determining a global optimal distribution result. Therefore, the power performance and the operation efficiency of the rail transit vehicle carrying the hybrid power source are improved.
