Abstract
A fuel cell system and a control method enables a smooth shift from a heat-up operation to a normal operation in a simple operating process. The fuel cell system includes a cell stack, an aqueous solution holding device having aqueous solution tanks which store aqueous methanol solution, and a first connecting portion and a second connecting portion which connect the aqueous solution tanks with each other, and a temperature sensor which detects a temperature of the aqueous methanol solution. Based on a result of a temperature detection, a setting is made for one of a first mode where the aqueous methanol solution in the aqueous solution tank is circulated to the cell stack and a second mode where the aqueous methanol solution in the aqueous solution tanks is circulated to the cell stack.
