DESIGN AND CONSTRUCTION OF ELECTROLYTIC CELLS FOR THE PRODUCTION OF HYDROGEN AT MEDIUM PRESSURE
The development of electrolytic cells, specifically conceived for the production of large quantities of hydrogen at medium pressure is the main object of this contract and is based on a critical review of commercial cell geometry and a complete analysis and optimization of the various parameters, experimentally obtained, of importance for the performance of large scale electrolysers. The result of this analysis have determined our final choice of a circular shaped cell having bipolar electrodes. Important objectives of our research have been the study on mass transfer and gas generation at the electrodes, on gas - liquid flow pattern inside the cell, on the selection of separators and electrolyte. The basic parameters of our research were limited to a maximum temperature of 140 degrees C and a maximum pressure of 30 bar. The completion of these studies in small cell models was followed by the design and construction of a larger electrolyser of four cells, each having an electrodic surface of 0.1 m**2. The electrolyser was successfully operated and all the necessary data was collected. In addition, a pilot plant, incorporating all the process control and the essential services to the electrolyser was designed, constructed and successfully operated. A 50.00 Nm**3/h hydrogen unit was basically designed and the investments and operating cost analyzed.
