The invention discloses a solid hydrogen storage fuel cell forklift system and a thermal management method thereof. The system comprises a fuel cell system, a power cell component and a hydrogen storage and buffer component. The method comprises the following steps: respectively calculating the released heat of the fuel cell system and the power cell and the absorbed heat of the hydrogen storage material and the heat absorption and energy storage material, and guiding the model selection of the cooling fan or the selection and consumption of the heat absorption and energy storage material according to a heat conservation relationship. According to the invention, a system overall heat management mode is adopted, so that heat generated by the galvanic pile or the power battery can be fully utilized, and the energy utilization efficiency is relatively high; a heat absorption and energy storage material is adopted for temperature regulation and control of the system, and high-power operation can be carried out under the condition that the heat dissipation capacity of the forklift is limited; the heat absorption and energy storage material can be stored to help the system to be quickly started at a low temperature, and the fuel cell is quickly heated and quickly started by heating the solid hydrogen storage device and the power cell; and rapid adjustment and distribution of energy can be realized.
