Abstract
A fuel cell system has produced water amount detection means that detects the amount of water produced in the fuel cell during low-efficiency operation of the system and gas supply limitation means that limits the amount of gas to be supplied to the fuel cell, based on the detected amount of water. The produced water amount detection means allows the amount of produced water to be correctly determined during low-efficiency operation of the fuel cell, thereby enabling the appropriate warm-up, and inhibits a condition, in which the amount of produced water is too large and warm up operation is hindered, to be generated. As a result, the amount of water produced during low-efficiency operation of the fuel cell is correctly determined and the appropriate warm-up is enabled.
