Measurement of Electric Current and Visualization of Bubbly Flow in Water Electrolysis
Details
Alkaline water electrolysis is the one of technologies of hydrogen production through decomposition of water by an electric power. The present study aims at improvement of hydrogen production in 'water electrolysis from viewpoint of generated bubbles' behavior, which interrupts the electric current between two electrodes. The measurement of electric current and the visualization of bubbly flow are practiced simultaneously to discuss the influence of the two-phase flow structure onto the water electrolysis. The paper describes two experiments on the micro-channel water electrolysis and on the water electrolysis by use of vibrating electrodes.
