Proton exchange membrane water electrolysis device

The invention provides a proton exchange membrane water electrolysis device which is a small hydrogen/oxygen generating device. The proton exchange membrane water electrolysis device comprises two anode plates, a negative bipolar plate and a membrane electrode between two anode plates and the negative bipolar plate; moreover, an anode end plate and an insulation spacer are sequentially arranged at two ends of the anode plate, sealing gaskets are respectively arranged between the anode plate and the membrane electrode and between the membrane electrode and the negative bipolar plate, and screw rods and nuts are used for fastening into the sealing gaskets, the anode plate, the membrane electrode and the negative bipolar plate into one body. The adopted working medium is pure water, the proton exchange membrane water electrolysis device has the characteristics of mild working conditions and high electrolytic efficiency, the purity of the produced gas is high, the operation is simple, and the proton exchange membrane water electrolysis device can be combined with a solar cell and a fuel cell to form a high-efficiency renewable energy utilization system.
