Abstract

A novel carbon fuel cell mode was designed for improving the cell performance on hybrid direct carbon fuel cells (HDCFCs). In this paper, the effects of Sn phase as the liquid anode on HDCFCs' performance was investigated. The comparative results indicated that the cell performance was strongly dependent on the amount of Sn loading. With selectivity of different weight ratios, 20 wt% Sn additive was optimized to be the best behavior, corresponding to considerably decreased ohmic and polarization resistance. However, other compositions showed inferior performance than that of Sn-free anode, probably due to the Li2SnO3 impurity formation impeding catalytic properties of liquid Sn and Li-K salt. Stability testing further implied the cell with 20 wt% Sn addition was the best choice because of maximum fuel efficiency and reasonable durability. Based on these results, the possible completing mechanisms of Sn participating in electrochemical reaction on HDCFCs were proposed.
