摘要： A fuel cell system is described that reduces ion elution and extends the life of an ion-exchange resin in a deionization unit of the fuel cell system. Based on a detected value from a conductivity meter and a measured value from a temperature sensor, a controller operates a three-way valve to control the flow rate of coolant passing through the deionization unit in order to regulate a reduction amount of conductivity of the coolant by the deionization unit. The controller controls the flow rate to maintain a relatively high level of conductivity at or within limit values allowed by the fuel cell stack, thereby extending the life of the ion exchange resin of the deionization unit.
