Abstract:
A fuel-cells system comprising a fuel cell which receives a supply of gaseous fuel containing at least hydrogen and a supply of oxidizing gas containing at least oxygen and generates an electromotive force through an electrochemical reaction of the gaseous fuel and the oxidizing gas, said fuel-cells system comprising:a cooling liquid feed unit which feeds a cooling liquid to said fuel cell, the cooling liquid passing through said fuel cell and thereby cooling down said fuel cell;a temperature distribution detection unit which detects a value reflecting a state of temperature distribution in said fuel cell; anda cooling liquid feed control unit which determines whether or not the state of temperature distribution in said fuel cell corresponds to a predetermined non-uniform state, based on the detection by said temperature distribution detection unit, and when the state of temperature distribution is determined to be the predetermined non-uniform state, controls said cooling liquid feed unit to increase a flow of the cooling liquid fed to said fuel cell per unit time.
