“…where the exchange current density j 0 was estimated to be 0.8 Â 10 23 A/cm 2 for the cell from the experimental data obtained by Qi et al [13]. Figure 4 shows a comparison of calculated cell voltage at varying current density with experimental results obtained from the Ballard Mark IV [5].…”

“…Although it has received little attention, CO is known to permeate through the membrane and to consequently degrade the performance of the cathode catalyst layer [13]. Using the model of CO transportation in the membrane, the effect on cathode performance is simulated in the model by using a CO induced degradation factor, Q, defined as …”

“…8,9 A byproduct of this reaction is CO; however, trace amounts of CO (>10 ppm) can poison a fuel cell electrode, drastically reducing its efficiency. [10][11][12] The CuCu 2 O-CuO system has been known to facilitate oxidation reactions in the bulk, suggesting it has potential as a costeffective substitute for noble metals in various catalytic systems. [13][14][15] Here we describe a cheap, effective method of using copper oxide nanoparticles loaded onto silica gel as an exceptional catalyst toward CO oxidation at relatively low temperatures.…”

“…Recently, several researchers have found that some impurities could migrate through the membrane from one side of the cell into the other side and poison the platinum catalyst on the two sides. Qi et al [10,11] studied the effect of CO in the anode on the performance of the PEMFC cathode. They found that CO could migrate through the membrane to poison the cathode catalyst and cause dramatic performance degradation.…”
