Abstract
Official abstract text for this publication.
A life prediction method according to the present disclosure is a life prediction method for a field cell apparatus including power generation units each including a fuel cell. The life prediction method includes predicting a time when each of the power generation units of the fuel cell apparatus reaches an end of life, from a cumulative power generation time of the power generation unit of the fuel cell apparatus at which the power generation unit is determined to reach the end of life, and from a ratio of a number of the power generation units that generate power out of a total number of the power generation units of the fuel cell apparatus in a predetermined period.
First claim
Opening claim text (preview).
What is claimed is: 1 . A life prediction method for a fuel cell apparatus including power generation units, the power generation units each including a fuel cell, the life prediction method comprising: predicting a time when each of the power generation units of the fuel cell apparatus reaches an end of life, from a cumulative power generation time of the power generation unit of the fuel cell apparatus at which the power generation unit is determined to reach the end of life, and from a ratio of a number of the power generation units that generate power out of a total number of the power generation units of the fuel cell apparatus in a predetermined period. 2 . The life prediction method according to claim 1 , wherein the cumulative power generation time of the power generation unit of the fuel cell apparatus at which the power generation unit is determined to reach the end of life is calculated based on a prediction of a decrease in voltage due to degradation of the power generation unit of the fuel cell apparatus. 3 . The life prediction method according to claim 1 , wherein the predetermined time includes time slots, and wherein the ratio is calculated as a first value divided by a second value, the first value being a summation, over the predetermined period, of a number of the power generation units that generate power in each of the time slots, the second value being the total number of the power generation units multiplied by a total number of the time slots included in the predetermined period. 4 . A life prediction apparatus for a fuel cell apparatus including power generation units, the power generation units each including a fuel cell, the life prediction apparatus comprising: a controller that predicts a time when each of the power generation units of the fuel cell apparatus reaches an end of life, from a cumulative power generation time of the power generation unit of the fuel cell apparatus at which the power generation unit is determined to reach the end of life, and from a ratio of a number of the power generation units that generate power out of a total number of the power generation units of the fuel cell apparatus in a predetermined period; and a communicator that communicates information to a display, the information indicating the predicted time when the power generation unit of the fuel cell apparatus reaches the end of life. 5 . A power generation system comprising: a fuel cell apparatus including power generation units, the power generation units each including a fuel cell; and the life prediction apparatus according to claim 4 .
