摘要：
PROBLEM TO BE SOLVED: To provide a concentration detecting system for a fuel cell for detecting more accurate fuel concentration by correcting the detection sensitivity of a fuel concentration detector varied by a by-product accompanying cell reaction, in the concentration detecting system for the fuel cell detecting the concentration of fuel supplied to the fuel cell.
SOLUTION: The detection sensitivity of a concentration detector is corrected with high concentration liquid fuel in which fuel concentration is known, pure water, or low concentration liquid fuel, and the methanol fuel concentration of measuring object is measured based on the characteristics of the detecting sensitivity of the obtained fuel concentration. By this constitution, since the detecting sensitivity of the fuel concentration detector varied by the by-product attendant on the cell reaction is corrected, the concentration of the high concentration liquid fuel and methanol fuel diluted with pure water or low concentration liquid fuel supplied to a stack is accurately detected, and the stack generates electric power with the supplied fuel having adequate concentration.
