Fuel cell system

Abstract

To suppress a failure of warming-up.SOLUTION: A fuel cell system comprises a fuel cell stack, a first DC / DC converter connected to the fuel cell stack, and a control section. The control section calculates a residual water amount of the fuel cell stack. The control section adjusts a supply amount of oxidant gas to the fuel cell stack so that a power generation amount of the fuel cell stack becomes a target warming-up power generation amount having correlation with the residual water amount. In performing control so that the power generation amount of the fuel cell stack becomes the target warming-up power generation amount, the control section performs the control so that the more the residual water amount is, the less the supply amount of the oxidant gas becomes.SELECTED DRAWING: Figure 3
