The invention discloses a differential pressure power generation device and a fuel cell vehicle, and solves the technical problem of unstable power generation while realizing energy recovery. The differential pressure power generation device comprises a main body, a power generator, an impeller and a bypass pipe, the main body is provided with a first cavity, a high-pressure pipeline and a low-pressure pipeline, wherein the high-pressure pipeline and the low-pressure pipeline are communicated with the first cavity, and pressure difference exists between a circulation inlet and a circulation outlet of the first cavity. The generator is arranged outside the first cavity; the impeller comprises blades and a rotating shaft; the blades are arranged in the first cavity, and the two ends of the rotating shaft are connected to the blades and a main shaft of the generator respectively; the bypass pipe is connected with the first cavity in parallel through the high-pressure pipeline and the low-pressure pipeline. At least one valve is arranged on the bypass pipe, the impeller converts pressure energy into rotating mechanical energy and drives the rotating shaft to rotate, the rotating shaft drives a main shaft of the generator to rotate, the generator converts the mechanical energy into electric energy, and the pressure energy released in the pressure reduction process is fully recycled.
