The utility model relates to the technical field of hydrogen fuel cells, in particular to a bipolar plate runner structure of a hydrogen fuel cell, which is characterized in that hydrogen is discharged into a runner region on the inner side wall of one group of bipolar plates, air is discharged into a runner region on the inner side wall of the other group of bipolar plates, and after the hydrogen and the air are uniformly distributed through the runner regions on the two groups of bipolar plates, the hydrogen and the air are uniformly distributed. Hydrogen enters the parallel areas on one group of bipolar plates, air enters the parallel areas on the other group of bipolar plates, the hydrogen in one group of bipolar plates forms current in the reaction mechanism, and the residual gas passes through the reaction mechanism and enters the other group of bipolar plates to react with oxygen in the air to form water vapor; the residual hydrogen in one group of bipolar plates is discharged through a gas outlet in o
