摘      要：This work describes the performance of the direct carbon fuel cell(DCFC)fuelled by ash-free *** coal in the DCFC might be problematic,mainly because of the ash deposition after the cell *** the study,the carbonaceous ash-free component of coal is obtained,which is then evaluated as the DCFC fuel and compared with raw coal,active carbon,carbon black,and *** electrolyte-supported SOFC structure is adapted to build the *** DCFC based on the ash-free coal fuel exhibits good performance with regard to the maximum power density,day-by-day measurements,and durability at continuous *** the carbon fuels are internally gasified to H2 and CO,the power density is generally much improved,compared to N2 pyrolysis *** power generation is most likely related to the concentration of pyrolyzed gases as well as the electrochemical reactivity of the solid carbon.
