AI Technical Summary
The durability development of existing fuel cell stacks relies on engineering experience and testing verification, which has a long iteration cycle and cannot meet the needs of rapid marketization. It also lacks positive design methods.
By obtaining the trained material degradation model and performance simulation model, and combining them with the current state parameters of the fuel cell stack, the degradation of materials and structures during stack operation is simulated, the stack voltage, impedance and leakage are predicted, and the predicted values are compared with the failure values to determine the remaining service life of the stack.
It enables high-precision prediction of fuel cell stack performance degradation, improves the applicability and speed of lifetime prediction, and meets the needs of rapid marketization.
