Patent ID: 7410715

Claim:
A fuel cell system, comprising: a circulatory device; and a fuel cell module, comprising: a membrane electrode assembly; an anode flow field plate, disposed at a side of the membrane electrode assembly and having an inlet and an outlet; and a heat exchange module, comprising: a fluid-conveying unit; and a heat exchange unit, wherein at least a part of the heat exchange unit is disposed inside the fluid-conveying unit to divide the fluid-conveying unit into a first channel and a second channel, the first channel communicates with the circulatory device and the inlet, the second channel communicates with the circulatory device and the outlet, the circulatory device is adapted for injecting a portion of a liquid reactant into the anode flow field plate from the inlet via the first channel and a remainder liquid reactant is discharged to the circulatory device from the outlet via the second channel.
