L'AUTONOME - AN ADVANCED AUTOMATIC ELECTROLYSER
An electrolyser working at 110 degrees C under a pressure of .4 MPa (4 bars absolute) has been built. A specially developed thin asbestos diaphragm, having an electric resistance of .2 OMEGA cm**2, is used. Catalysis is obtained with Raney nickel at the cathode and perovskite (Sr-.5,La-.5)CoO-3 deposited on Raney nickel at the anode. Electrodes are bipolar with elastic forelectrodes designed to obtain a zero gap between them and the diaphragm. The electrolyte circulates by gas lift, all functions of start up, monitoring and emergency shut down are computerized. A stack composed of 4 cells of .2 m**2 has been assembled and run for 300 hours at 800 A. A 20 cells stack with catalyzed electrodes is under development, results will be given at the conference.
