The utility model belongs to the technical field of electrolytic baths, and particularly relates to a pure water
hydrogen production PEM electrolytic bath structure which comprises an
anode plate and a
cathode plate, the
anode plate is provided with an
oxygen outlet and a water inlet, the water inlet is fixedly provided with a first connecting shell and a second connecting shell, the first connecting shell is symmetrically provided with connecting assemblies, and the second connecting shell is fixedly provided with a second connecting shell. A filter screen is arranged on the frame and located on one side of the water inlet. According to the utility model, pure water can be conveniently filtered by the filter screen, tiny impurities in the pure water can be intercepted by the filter screen,
water flow containing the impurities is prevented from entering the electrolytic bath, when the filter screen is regularly cleaned, the first connecting shell is detached from the second connecting shell by operating the connecting
assembly, and then the frame is pulled to move out of the second connecting shell, so that the filter screen is cleaned; the filter screen is arranged on the filter screen to clean impurities on the filter screen, blockage of the filter screen caused by
impurity accumulation is avoided, adverse effects of mechanical impurities possibly contained in pure water on the
electrolysis process are avoided by filtering the pure water, and the purity of
hydrogen produced by the electrolytic bath is improved.
