Novel water electrolysis hydrogen production system

The utility model discloses a novel water electrolysis hydrogen production system, which comprises an alkali liquor heater I used for providing hot alkali liquor for a water electrolysis hydrogen production device and a gas-liquid separation device II used for washing gas output by the water electrolysis hydrogen production device, and is suitable for achieving different experimental purposes through various pipeline connection modes. The alkali liquor heater I can reduce the heat exchange temperature of the coil pipe, reduce the heat exchange area and reduce the corrosion risk of alkali liquor to the coil pipe; the electric heating tube is completely soaked in saturated water vapor, and the hidden danger of high-temperature open fire is avoided. According to the gas-liquid separation device II, the gas-liquid separation function and the gas washing function in the system are combined into a whole, external pipeline connection between equipment is reduced, integration of the equipment is facilitated, use is m
