<P>PROBLEM TO BE SOLVED: To provide a fuel cell device capable of improving the power generation efficiency by supplying fuel gas of an optimum flow rate. <P>SOLUTION: This fuel cell device comprises a solid electrolyte fuel cell 31, and a fuel gas supplying device 33 for supplying hydrogen to the solid electrolyte fuel cell 31. The fuel gas supplying device 33 comprises a reformer 53 for reforming hydrocarbon gas to hydrogen, a pump 45 for supplying hydrocarbon gas to the reformer 53, and a relief valve 51 which opens at a pressure greater than the gas pressure on the upstream side, or a zero governor 61 which adjusts the gas pressure on the downstream side to the atmospheric pressure, disposed at the upstream side of the pump 45. <P>COPYRIGHT: (C)2008,JPO&INPIT |
