SPE high-purity hydrogen generator

The utility model relates to the technical field of hydrogen generators, in particular to an SPE high-purity hydrogen generator which comprises a reaction box, a clamping strip, a clamping groove, a cover plate and a clamping shaft, the cover plate is driven to move through a telescopic air cylinder, so that the cover plate is moved away from the upper part of the reaction box, then a proton exchange membrane is directly drawn out from a limiting strip, and then the reaction box is closed. Then, a new proton exchange membrane is clamped with the limiting strip, then the opening frame is pressed to drive the guide shaft to move, after the clamping blocks do not clamp the electrode, the electrode is pulled out and a new electrode is replaced, the opening frame is loosened, the clamping blocks are driven by the supporting springs to clamp the electrode, and therefore the electrode replacement is conveniently and rapidly completed; the cover plate is driven to move through the telescopic air cylinder, and when th
