The invention relates to the technical field of fuel cells, and provides a fuel cell vehicle hydrogen leakage monitoring method, device and equipment and a medium, and the method comprises the steps: obtaining hydrogen leakage change characteristic data at a plurality of preset positions in a fuel cell vehicle; pre-processing the hydrogen leakage change characteristic data at the plurality of positions according to a preset data specification to obtain the pre-processed hydrogen leakage change characteristic data at the plurality of positions; and transmitting the preprocessed hydrogen leakage change characteristic data at the plurality of positions to a pre-trained hydrogen leakage monitoring model to obtain a hydrogen leakage monitoring result. According to the hydrogen leakage monitoring method and device, the accuracy of the hydrogen leakage monitoring result is improved through the hydrogen leakage change characteristic data of the multiple positions and the hydrogen leakage level and the hydrogen leakag
