Zusammenfassung:	The present utility provides a fuel battery polar plate which comprise flow field including guide groove and small groove which is at bottom of guide groove, so the flow field cross section is composite groove structure. In the course of fuel battery reaction, product is easy to be congregated at small groove of composite groove structure and conveniently be discharged outside battery and not easy to block flow passage that is guide groove, which keep it stable of the battery performance.
