Effect of oxygen storage materials on the performance of proton-exchange membrane fuel cells

摘要

Oxygen storage materials with a chemical composition of Ce_(0.8)Zr_(0.2)O_2 and V_2O_5, were prepared and incorporated into the cathode catalyst layer of proton-exchange membrane fuel cells, respectively. The presence of Ce_(0.8)Zr_(0.2)O_2 slightly enhanced the performance of the fuel cell, but the incorporation of V_2O_5 largely decreased the fuel cell performance.
