MASS SPECTROMETRIC STUDIES OF HYDROGEN GENERATION UNDER ELECTROLYSIS PROCESS WITH THE USING TUBE CATALITYC ELECTRODES

The work presents some experimental results obtained in the new module construction of an electrolyzer with tube electrodes: mass spectra of the mixtures of gases, generated during electrolysis, volt-ampere characteristics, etc. It has been shown that at electrolytes (H2O + 1 wt.% NaHCO3, H2O + 1 wt.% Na2CO3) temperature of ~ 50 °C and a pressure in the electrolyzer chamber of ~ 2 atm, the generated gas is 92 vol.% consists of hydrogen. Estimations show from two to four times (in dependence on electrolyte composition) higher effectiveness of converting electri-cal energy into the amount of electrolysis gas for new electrolysis setup construction compared to the previous ver-sion.
