Fuel cell cooling system

摘要

A circulation pipe for a coolant is connected to a fuel cell. A pump and a heat exchanger are connected to the circulation pipe. A bypass pipe is connected in parallel with the pump. An ion exchanger is connected to the bypass pipe. An electronic cooling device is connected to the bypass pipe on an upstream side of the ion exchanger. The coolant, which is supplied to the ion exchanger, is cooled by the electronic cooling device to a predetermined temperature, so that the ion-exchange resins are prevented from being abnormally heated by the coolant.

1. A fuel cell cooling system, comprising:
a circulation pipe connected to a fuel cell to circulate a coolant; a pump connected to the circulation pipe to circulate the coolant; a heat exchanger connected to the circulation pipe to cool the coolant; an ion exchanger configured to adsorb and remove impurity ions from the coolant in the circulation pipe; a temperature sensor configured to monitor a temperature of the coolant at a downstream side of the heat exchanger; and a controller programmed to operate a cooler that is provided on at least one of the ion exchanger and the circulation pipe on an upstream side of the ion exchanger and is configured to cool the coolant to no more than a predetermined temperature when the temperature of the coolant at the downstream side of the heat exchanger exceeds the predetermined temperature.
