Direct carbon fuel cell design for continuous operation

The design of a direct carbon fuel cell (DCFC) for continuous operation was successfully executed and is presented in this study. Petroleum coke, an abundant source Canada, used as pneumatically supplied to the anode side cell. open circuit voltage (OCV) reached 1.1 V generated power density 28 mW/cm2 at 700 °C 85 850 °C. After about 180 h cell's performance declined, due loss electrolyte. In next design, fabricated with electrolyte circulation loop. This lower than first assembly but its OCV drop during significantly improved. These are molten carbonate DCFC results demonstrating supply recirculation potential ash impurities removal.
