CO tolerant RuSx/C electocatalystas the anode in a polymer electrolyte membrane fuel cell |
| 초록 |
To solve problems regarding the high cost of platinum and CO poisoning in a polymer electrolyte membrane fuel cell (PEMFC), a platinum-free electrocatalyst with high CO tolerance needs to be developed for use as the anode in a PEMFC. In the present study, we tried to apply carbon supported RuSxto the anode of a PEMFC as its catalytic activity for hydrogen dissociation is well known. The CO tolerance of RuSx/C was high because the sulfur atoms were expected to block the adsorption sites of CO molecules. We prepared RuSx/C using a sonochemical method in order to allow high dispersion of RuSx particles on the carbon support. |
