This invention discloses a method for predicting the water content of the cathode flow channel in a visualized cathode fuel cell device, belonging to the field of fuel cell visualization. The method includes an anode unit, a cathode unit, and an MEA (Mechanical and Electrical Assembly). The cathode unit has a transparent end plate with a hollow cavity.

A difference image is obtained through difference calculation, and then a binary image is obtained through adaptive binarization. The water coverage rate is calculated using a mask image as a quantitative representation of the water content. A convolutional neural network is constructed, and the model is trained using the water coverage rate as input. The Sobol sensitivity analysis method is used to optimize the hyperparameters of the learning rate, dropout rate, and batch size. The optimized CNN model is used to predict the water content in the cathode flow channel in real time, providing a basis for flood warning.
