Factors That Determine the Performance of Carbon Fuels in the Direct Carbon Fuel Cell

The direct carbon fuel cell (DCFC) is a promising power generation device, which has a much higher efficiency (80%) and a lower emission than conventional coal-fired power plants. In this study, different commercial carbon fuels including activated carbon (AC), carbon black (CB220 and CB660), and graphitic carbon (GC) were tested in DCFC at 600−800 °C. The relationship between the intrinsic properties of carbon fuels and their electrochemical...
