[PROBLEMS] To provide a method for desulfurization with a desulfurizing agent, which can efficiently desulfurize, for example, a hydrocarbon oil as a raw material and fuel for generating hydrogen for use in fuel cells, particularly kerosenes and light oils, without the need to use reduction treatment and hydrogen and at a temperature from room temperature to about 100°C, and a fuel cell system using the desulfurization method. There are also provided a solid acid useful as a constituent of the desulfurizing agent for use in the desulfurization method, and a process for producing the solid acid. [MEANS FOR SOLVING PROBLEMS] A solid acid comprising 20 to 99.9% by mass of aluminum oxide and 0.10 to 3.00% by mass of sulfur and having a specific surface area of not less than 150 m2/g and a pore volume of not less than 0.35 ml/g, and an I1540/I1450 ratio of 0.12 or less, wherein I1450 represents a peak height of a peak (1450 ± 5 cm-1) attributable to a Lewis acid site as measured by pyridine adsorption Fourier transform infrared spectroscopy, and I1540 represents a peak height of a peak (1540 ± 5 cm-1) attributable to a Broensted acid site, and a process for producing the solid acid, a method for desulfurizing a hydrocarbon oil using the solid acid as a desulfurizing agent, and a fuel cell system using the desulfurization method.
