Abstract
A flow field plate module for a fuel cell system includes at least one flow field plate defining a fuel transporting channel thereon. The fuel transporting channel is divided into a middle converging zone having a group of first flow guiding plates arranged therein, and two diverging zones located at two lateral sides of the middle converging zone and each having a group of second flow guiding plates arranged therein. The second flow guiding plates are symmetrically arranged in the two diverging zones and are directed at respective inner end toward a space between two adjacent first flow guiding plates in the middle converging zone to thereby offset from each of the two adjacent first flow guiding plates by a predetermined distance in a fuel flowing direction, so that a fluid path is formed between any two adjacent first and second flow guiding plates.
