Modular hydrogen fuel cell system

The utility model discloses a modularized hydrogen fuel cell system which comprises a hydrogen supply module, an air supply module, an electric pile module and a central control system, and the hydrogen supply module is used for providing hydrogen for the electric pile module; the air supply module is used for providing air for the electric pile module; the electric pile module is used for converting chemical energy of hydrogen introduced from the hydrogen supply module and air introduced from the air supply module into electric energy; a cooling device is arranged in the electric pile module; and the central control system can synchronously control and monitor the running states of the hydrogen supply module, the air supply module and the electric pile module. According to the modularized hydrogen fuel cell system, a plurality of modules are arranged and the central control system is arranged for unified control, so that the monitoring effect on each component is improved; the risk that the overall operation
