Fuel manufacturing system

Abstract

The present invention relates to a fuel manufacturing system and has an object to provide a fuel manufacturing system which can simplify in term of the system construction. An electrolytic solution having a property of absorbing CO 2 is used in the system. Therefore, a mixed gas can be generated directly with the electrolytic solution in which CO 2 has absorbed. In short, a CO 2 absorbing process is only needed to execute, which is shown in FIG. 6 . Thus, the mixed gas generating process can be simplified as compared to a system including the CO 2 releasing process (FIG. 4, 5 ). And the system construction can be downsized since a device for the CO 2 releasing process can be omitted.
