Abstract
A bipolar plate includes a plurality of flow channels for fuel flow, wherein the flow channels are divided into a plurality of sections along a direction of the fuel flow. The total cross-sectional area of the flow channels across the sections becomes smaller from a fuel inlet toward a fuel outlet. A plurality of protrusions are formed between the sections, and the protrusions mix a fuel that passes through the flow channels. A fuel cell includes membrane electrode assemblies interposed between a plurality of the bipolar plates.
