Abstract
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.
