Title:
燃料電池車の出力診断装置
Document Type and Number:
Japanese Patent JP4016536
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an output diagnostic device of a fuel cell vehicle capable of continuing driving without stopping driving of a vehicle until a warning is issued even when long deterioration exis to in a fuel cell. SOLUTION: The specified amount of current is previously controlled by a fuel cell control device 51 so that when a vehicle is stopped, it is outputted to a secondary battery 21 for the specified time from a fuel cell stack 15, and output voltage outputted from the fuel cell stack 15 is detected with a stack voltage sensor 35 and memorized in an inner ROM. The present value relating to the output value of the fuel cell stack 15 is compared with an initial value previously memorized to find an output decreasing ratio, and the maximum power capable of outputting from the fuel cell stack 15 is corrected in a accordance with the output decreasing ratio.
