Open the CIPO recordAbstract From the Canadian patent
The activity of catalysts used in promoting the oxidation of certain oxidizable species in fluids can be enhanced via electrochemical methods e.g. NEMCA. In particular, the activity of catalysts used in the selective oxidation of, carbon monoxide can be enhanced. A purification system that exploits this effect is, useful in purifying reformate supplied as fuel to a solid polymer electrolyte fuel cell, stack. The purification system comprises an electrolytic cell with fluid diffusion, electrodes. The activity of catalyst incorporated in the cell anode is enhanced.
