Under normal operating conditions using humidified hydrogen and air, the performance of a single cell is not uniform over the active electrode area due to non-uniform distribution of reactant gases and water. To improve catalyst utilization, a catalyst-gradient electrode method is applied to a single-cell fabrication. This procedure is found to be very effective in reducing platinum usage without loss in cell performance. (c) 2007 Published by Elsevier B.V.
