  • Publication number: 20230393208
    Abstract: A system includes a first storage unit configured to store a result of an endurance test actually carried out over a first period under a first use condition as training data, and a first arithmetic unit having a machine learning model configured to perform machine learning using the training data stored in the first storage unit. The machine learning model is configured to estimate a result when the endurance test is carried out under a second use condition. The first use condition is a use condition in which a predetermined operation parameter that influences degradation of the fuel cell system appears with equal frequency over an entire domain of the operation parameter. The second use condition is a use condition in which the operation parameter appears with unequal frequency in at least part of the domain of the operation parameter.
