This invention discloses an air-cooled fuel cell based on a series flow field, comprising: a fuel cell stack with an installation end face; a series flow field structure integrated on the fuel cell stack, including independently connected cooling channels, a flow splitter assembly, and a cathode reaction channel; wherein, the independently connected cooling channels have an independent cooling channel inlet and an independent cooling channel outlet, both disposed on the installation end face; the cathode reaction channel has a cathode reaction channel inlet and a cathode reaction channel outlet, both disposed on the installation end face; the flow splitter assembly is disposed on the outer side of the installation end face and connects the outlet of the independently connected cooling channels to the inlet of the cathode reaction channel; and a fan is disposed on the installation end face and connected to the inlet of the independently connected cooling channels. This invention enables a single fan to supply air to both the independently connected cooling channels and the cathode reaction channel, while simultaneously decoupling the flow rates of the two channels, thereby improving the power generation performance and operational reliability of the air-cooled fuel cell.
