Performance improvement of PEFC modules with cell containing low amount of platinum
- SANYO Electric Co., Ltd., Osaka (Japan); and others
Cell components of the PEFC module were studied to improve the module performance. The cell performance in a high air utilization region was improved by selecting an air channel design of the separator in which high air flow speed was obtained. Optimization of Teflon{reg_sign} amount on the cathode backing carbon paper also contributed the cell performance. Modifications of the gas channel design and the backing carbon paper were carried out in a 200 cm{sup 2} x 20-cell module and 36-cell module. Dependence of air utilization on module performance was remarkably improved and power density of more than 0.3 W/cm{sup 2} was achieved in spite of the platinum amount in the cells was decreased to 1.1 Mg/cm{sup 2}.
