PROBLEM TO BE SOLVED: To provide an industrial vehicle capable of diagnosing a deterioration state of a fuel cell without trouble, easily, more safely and at lower cost without requiring any special diagnostic device or inspection facility for diagnosing the deterioration state of the fuel cell, and a deterioration diagnosis method of the fuel cell in the industrial vehicle with the fuel cell.SOLUTION: The industrial vehicle comprises: a fuel cell 11A; loading work means 30A and travel means 30B using power of the fuel cell; cell deterioration diagnosis means 20; and storage means. The storage means stores an initial load output property of the fuel cell in the case where a predetermined load is operated. After execution of deterioration diagnosis is instructed, the cell deterioration diagnosis means determines a deterioration state of the fuel cell on the basis of a diagnosis time load output property of the fuel cell which is detected in the case where the predetermined load is operated, and the initial load output property. The predetermined load which is operated and consumes power when determining the initial load output property and the diagnosis time load output property, is the loading work means which is operated in a travel stop state. |
