Abstract

The paper presents a method of hydrogen sampling from an electrolysis cell for further analysis of the composition of the generated gas. Solving the problem of hydrogen sampling, the system "electrolytic cell - hydrogen separator - gas pipette filled with distilled water" was used. The system ensures the supply of hydrogen produced in the electrolysis cell to the gas pipette without mixing with atmospheric gases. Sampling of hydrogen (oxygen) directly from the electrolyzer for further analysis was carried out without evacuating the gas storage tanks and connecting pipelines. The purpose of the work is the development and testing of indirect sampling of hydrogen from an electrolysis cell without vacuuming additional equipment. The developed method of indirect selection ensures the purity and representativeness of the gas sample generated in the electrolysis cell. The system makes it possible to transport the hydrogen produced in the electrolysis cell to the gas pipette without mixing it with atmospheric gases. Slowly filling the gas pipette with the accumulated generated hydrogen allows you to completely squeeze the distillate out of it without remaining drops of liquid on the walls of the pipette.
