<P>PROBLEM TO BE SOLVED: To solve problems that, in a fuel cell system to circulate exhaust fuel gas exhausted from a fuel cell, there is no sufficient steam in the exhaust fuel gas, temperature of mixed gas is reduced when vaporizing liquid fuel, and carbon deposition is generated. <P>SOLUTION: Since the system is equipped with a fuel vaporization means 2 to vaporize the liquid fuel sprayed from a fuel sprayer 1, a fuel reforming means 3 to make the fuel gas by reforming vaporizing fuel from the fuel vaporization means 2, a primary air introducing means A1 to introduce a primary air into a route from a fuel gas exhaust part of the fuel cell FC to the fuel vaporization means 2, a secondary air introducing means A2 to introduce secondary air into the route from the fuel vaporization means 2 to the fuel reforming means 3, and a reforming heating means 4 to heat the fuel reforming means 3, by carrying out partial burning in the fuel vaporization means 2, steam and heat are formed, and the liquid fuel can be vaporized without generating the carbon deposition. <P>COPYRIGHT: (C)2010,JPO&INPIT |
