  • Publication number: 20080241611
    Abstract: A direct internal reforming system of ethanol for a molten carbonate fuel cell (MCFC) is provided. An MCFC anode for a direct internal reforming of ethanol, a manufacturing process thereof, and a direct internal reforming method in MCFC where an ethanol solution is injected into the anode are provided. by the simple process of coating the surface of the anode with small quantity of catalyst, the drawback in that the performance of MCFC is degraded when the ethanol is directly used as a fuel is overcome. Further, an additional apparatus such as an external reforming apparatus and additional cost for pelletizing the catalyst powders are not required, which is economical. Furthermore, the performance improvement enables long-term operation, which contributes to commercialization of MCFC.
