(57) [Problem] To efficiently produce hydrogen, and to reduce the deterioration of the reforming catalyst without adversely affecting the reforming catalyst, the partial oxidation catalyst, and the fuel cell electrode, and to transport the vehicle and the like. To provide fuel oil for fuel cells suitable for use in fuel cells. SOLUTION: After fractionating a reformed gasoline into a low-boiling fraction, a medium-boiling fraction containing benzene and a high-boiling fraction, a transport gas comprising a residual obtained by removing benzene from the medium-boiling fraction is used. Fuel oil for fuel cells. |
