A fuel cell system whose fuel loss caused by the crossover of the fuel is small and which can be operated economically. The fuel cell system includes a fuel cell, a primary feeding systemfor feeding a primary fuel which is a liquid fuel to the fuel cell, a secondary feeding systemfor feeding a secondary fuel which is a liquid fuel whose saturation vapor pressure is lower than that of the primary fuel to the fuel cell, a ECUfor controlling each part so that the primary fuel in the fuel cell is replaced with the secondary fuel when terminating the operation of the fuel cell

Fuel cell system

A main object of the present invention is to provide a method for producing a carbon nanofiber supporting a metal fine particle in which the metal fine particles are supported in high dispersion and sintering of the metal fine particles is restrained. The present invention attains the object by providing a method for producing a carbon nanofiber supporting a metal fine particle comprising a step of: spinning a material composition which contains a nitrogen-containing polymer, including a nitrogen element and capable of forming a carbon nanofiber, and an organometallic compound by an electro spinning process, and the spinning is conducted under a condition which keeps the nitrogen element remained to the carbon nanofiber and allows the formation of the carbon nanofiber.
