摘要： PROBLEM TO BE SOLVED: To avoid an oversupply of water to an anode by controlling circulation amount of exhausted gas based on an accurately estimated water content in the exhausted gas in a fuel battery device in which the exhausted gas from the anode is sent back to the anode again. SOLUTION: The fuel battery device includes a fuel cell stack composed of laminated fuel battery cells supplying hydrogen-containing gas to the anode, a circulating passage where the exhausted gas from the anode is again sent to the anode with a variable-capacity pump, a gas-liquid separation device mounted in the circulating passage, and a drain valve which exhausts liquid water from the gas-liquid separation device to the circulation passage. The fuel battery device provides a means that estimates an amount of the water inflow at the gas-liquid separation device, and an amount of drain water exhausted from the drain valve. The oversupply of water to the anode is avoided in such a manner that, the more the difference is between the amounts of the water inflow and the drain water, the less amount of the exhausted gas is returned to the anode.
