ABSTRACT:
A fuel cell stack1in a fuel-circulating fuel cell system is supplied with fuel and an oxidizing agent to generate electricity. The fuel discharged from the fuel cell stack1is supplied to the fuel cell stack1again through a fuel-circulating passage6.In the fuel-circulating passage6is provided a fuel pump3powered from an outside source to circulate the fuel through the fuel-circulating passage6at a predetermined circulation rate. An ECU4transmits an output instruction value to the fuel cell stack1and regulates a circulation rate of the fuel in the fuel-circulating passage6according to the output instruction value.
