DIAGNOSTIC APPARATUS AND DIAGNOSTIC METHOD FOR FUEL CELL

摘要

According to an aspect of the invention, a diagnostic apparatus (20) which diagnoses a state of the fuel cell (122) includes an operation device which is used for operating the fuel cell (122); operational state detecting means (60) for detecting a change in an operational state (I, V) of the fuel cell (122); device control means (60) for controlli ng the operation device such that the fuel cell (122) is operated according to at least one predetermined operation pattern; and diagnostic means (60) for diagnosing the state of the fuel cell ( 122) based on the change in the operational state (I, V) of the fuel cell (122) that is detected by the change in the operational state detecting means (60) when the fuel cell (122) is operated by the device control means (60) according to the at least one predetermined operation pattern, and the at least one predetermined operation pattern.
