The invention relates to the technical field of fuel cells, and discloses a fuel cell vehicle hydrogen leakage early warning and positioning method and device, and the method comprises the steps: obtaining first target data fed back by each sensor in a target vehicle, the first target data comprising sensor position information and hydrogen release concentration data; inputting the first target data into a trained first model to obtain second target data; inputting the second target data into a trained second model to obtain prediction data, the second model being used for determining predicted hydrogen release concentration data and predicted leakage probability corresponding to the position information of each sensor based on the second target data; and determining an early warning result based on a preset early warning threshold value and the prediction data. According to the method and the device, the position information of the hydrogen concentration is considered, and the hydrogen release concentration and the leakage probability of each sensor position can be finely predicted through the deep separable convolution processing and the processing of the second model.
