Abstract
The present invention is to prevent the temperature of an electric heater from being higher than or equal to a temperature at which control to reduce power consumption is started to prevent an abrupt decrease in the power consumption of the electric heater in order to secure a power consuming destination of a fuel cell. A fuel cell systemincludes: a fuel cellthat receives the supply of reactant gas to generate power; a fuel cell cooling systemfor circulating a coolant through the fuel cellto cool the fuel cell; an electric heateroperated to consume power of the fuel celland driven to decrease power consumption abruptly at a temperature lower than a decomposition temperature of the coolant; and a heater cooling systemfor circulating the coolant around the electric heaterto cool the electric heater. In a control method therefor, when the temperature of the coolant in the heater cooling systemfalls within a temperature range where the power consumption of the electric heaterchanges abruptly, the coolant is circulated from the fuel cell cooling systeminto the heater cooling systemto cool the electric heater
