Abstract

To identify an electrocatalyst that can effectively generate power and reduce CO2, we measured the power generation characteristics of a polymer electrolyte fuel cell fed with H2 and CO2 to the anode (Pt/C) and cathode (Pt(1−x)Rux/C), respectively. The obtained power generation characteristics were compared to their corresponding CO2 reduction characteristics. A trade-off relationship between the CO2 reduction and power generation performances was observed. Overall, the Pt0.8Ru0.2/C electrocatalyst has the potential to be an efficient cathodic catalyst in a H2-CO2 fuel cell that reduces CO2 while generating power.
