Title:
METHOD AND APPARATUS FOR PREDICTING REMAINING LIFE OF FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2023/000985
Kind Code:
A1
Abstract:
A method and apparatus for predicting the remaining life of a fuel cell. A fuel cell is composed of a plurality of units. The method for predicting the remaining life of a fuel cell comprises: acquiring parameter data of a fuel cell within an operating working condition period, wherein the parameter data at least comprises a voltage, a current, a unit voltage, an air intake flow, an air intake pressure and a cooling water inlet temperature (S101); acquiring a fused health index according to the parameter data, and acquiring a health state value of the fuel cell according to the fused health index (S102); acquiring a behavior of the fuel cell within the operating working condition period, wherein the behavior at least comprises starting, stopping, load changing and fault emergency stopping (S103); and training a long short-term memory neural network model according to a time, the health state value and the behavior, and predicting the remaining life of the fuel cell according to the long short-term memory neural network model (S104).
