用于燃料电池汽车重整器的CO脱除技术

Methods of CO clean-up for the reformer of fuel cell vehicles

烃类重整产生的氢气中含有的CO会使燃料电池的Pt电极中毒 ,必须将其控制在极低的浓度水平。

Energy shortage and environment problems make hydrogen fuel cell become the alternative for automotive power system Hydrogen can be supplied on board by reforming hydrocarbon fuels However, the reformate contains CO, which will poison the platinum anode catalyst of fuel cell The concentration of CO must be controlled under extremely low level In this paper, the methods of CO clean up in H 2 rich gases and the current status of their applications in fuel cell vehicles reformer are reviewed
