<P>PROBLEM TO BE SOLVED: To prevent excess increase in fuel gas pressure supplied to a fuel cell without putting exceptional limit on design in a fuel cell system. <P>SOLUTION: The fuel cell system 10 including the fuel cell 22 is equipped with a hydrogen supply passage 60 supplying hydrogen-containing fuel gas to the fuel cell 22, a first pressure sensor 52 detecting the pressure in the hydrogen supply passage 60, a shutting valve 61 blocking the hydrogen supply passage 60 in a closing state, and a supply stop control part making the shutting valve 61 in the closing state when the pressure in the hydrogen supply passage 60 detected with the pressure sensor 52 exceeds a first reference value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
