Fuel cell low-voltage regulation module

The utility model discloses a low-voltage regulating module of a fuel cell, and belongs to the technical field of hydrogen supply of fuel cells. The problems that the safety performance is reduced dueto the fact that discrete components are adopted for low-voltage adjustment of an existing fuel cell, the structure is complex, the number of components is large, and the number of interfaces is large, and real-time adjustment and control cannot be achieved through an adopted mechanical pressure reducing valve are solved. The fuel cell pressure adjusting module comprises a pressure reducing valve, a flame arrester with a filtering function, a module body, a stop valve, a safety valve and a connecting port used for being connected with a pressure sensor. Wherein a cavity, an air inlet and an air outlet are formed in the module body; the cavity is communicated with the air inlet; wherein the cavity is provided with a gas inlet and a gas outlet, a flame arrester with a filtering function isarranged at the gas inlet,
