제목 Performance Characteristics of a Tubular Direct Carbon Fuel Cell Stack Coupled with Dry Coal Gasifier
초록 A carbon gasified-direct carbon fuel cell (DCFC) stack has been fabricated and investigated for producing effective carbon fuel cell reaction. The anode-supported tubular cells with 45 cm2 active area were used for making the DCFC stack, which was coupled with a reverse boudouard reaction fluidized bed gasifier. The activated carbon (BET area 1800 m2/g) powder was mixed with K2CO3 powder and the mixed carbon powders as fuel were supplied to the fluidized bed and the direct carbon fuel cell stack by flowing CO2. The induced CO fuel by a reverse boudouard reaction at the fluidized bed reactor increased the stack performance. The tubular DCFC stack showed a maximum power of 30 W at 750 oC; it was operated at variable operating conditions: operating temperature, flow rates of CO2 and anode gas composition. These results indicate that the fabricated tubular DCFC is a promising candidate of power generator for many other practical applications, such as residential power generation (RPG) and stationary power systems.
