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

Oxygen storage materials with a chemical composition of Ce0.8Zr0.2O2 and V2O5, were prepared and incorporated into the cathode catalyst layer of proton-exchange membrane fuel cells, respectively. The presence of Ce0.8Zr0.2O2 slightly enhanced the performance of the fuel cell, but the incorporation of V2O5 largely decreased the fuel cell performance.
