| A fuel cell bipolar flow field plate and a fuel cell stack are provided.  The fuel cell bipolar flow field plate includes a first gas channel and a second gas channel.  Each of the gas channels has several sub-channels, each of the sub-channels has bending parts, and adjacent sub-channels have opposite flow directions.  The sub-channels of the two gas channels form a four-leaf clover type pattern in a reaction area of the fuel cell bipolar flow field plate.  A bending angle of each of the bending parts in the four-leaf clover type pattern is within 90 degrees. |
