【 摘 要 】

In order to research the discharge properties of the direct carbon fuel cell (DCFC) with a molten metal anode, the experimental system with a reactor is designed and constructed. The reaction mechanisms at both anode and cathode are analyzed. The molten Sn and Sb are used as the anodic material for comparison. The cell performance of DCFC is tested before and after discharging in the battery mode and the carbon fuel mode, respectively. In the battery mode, due to the different states of metallic oxides, the current density is not degraded after discharging with the molten Sb anode, but sharply decreases with the molten Sn anode. On the contrary, the cell performance with Sb is much worse than that with Sn after discharging in the carbon fuel mode, which is result from the volatility of Sb together with the reduction of its oxide. The above studies will help to thoroughly understand the underlying mechanism of DCFC with a molten metal anode.
