Abstract

Current distributions in a PEM fuel cell with interdigitated flow fields were measured with the current distribution measurement gasket technique. The measurement results showed that current density distribution in a fuel cell with interdigitated flow fields is much more uniform than those observed in a fuel cell with serpentine flow fields, especially at low reactant gas flows. The more uniform current distribution can be attributed to more uniform flow distribution over the flow fields. Measurement results also showed that interdigitated flow fields have very good water removal capability and no flooding phenomena were observed at high humidification temperatures; while at low humidification temperatures, the effect of drying is more severe than that found in serpentine flow fields.
