Abstract
The effect of physical properties of coal fuels and carbon particle on performance of DCFC (Direct Carbon Fuel Cell) was investigated. Shenhua and Adaro were selected as coal fuel and carbon particle was used for comparing with coal. The Ultimate, proximate, SEM, XRD, and BET analysis of samples were conducted. The component of char was more important than that of raw coal because the operating temperature of reactor is higher than devolatilization region of coal. The surface area and volume of pores affected significantly the performance of the system than content of fixed carbon or char rates. The performance of DCFC with carbon particle was in proportional to working temperature.
