Title:
LEARNING DEVICE
Document Type and Number:
Japanese Patent JP2021034338
Kind Code:
A
Abstract:
To execute building of a learning model efficiently, and to reduce occurrence of delayed discovery or oversight of deterioration of the current voltage characteristics of a fuel cell.SOLUTION: A learning device for learning the current voltage characteristics of a fuel cell, and detecting deterioration of the current voltage characteristics of a fuel cell is equipped with a first operation part 12 for filtering the data where the fuel cell stack temperature is equal to or larger than a certain value, and the temperature at a part of large heat capacity in the circuit is equal to or larger than a certain value, out of the collected data, and a second operation part 13 performing building of a learning model, and detection of the current voltage characteristics of the fuel cell by using the data filtered by the first operation part 12.SELECTED DRAWING: Figure 1
