A simulation and experimental study was carried out for estimating the performance of an DDFC (Direct Dimethyl Ether Fuel Cell) exhaust gas recovery system which was designed for abstraction of DME (Dimethyl Ether) from CO_2 in DDFC exhaust gas and recirculation of DME to the cell by dissolving DME into water. The simulation results show that the recovery ration reached to 80% with a DME oversupply ratio of 150% and a solubility of DME to pure water of 5wt.%. The simulation results also show that an equilibrium beteew water comsurption for fuel humudification and water production by water generationg reaction in cathode side could be kept at the temperature of recovery system <48℃. The experimental results show that the cell output current increased when the exhaust gas was absorbed by water and the absorbent wasrecycled.
