摘要
The concentration overpotential due to dissolved gas generated at electrodes turns out to be the result of several mass-transfer mechanisms acting simultaneously and with mutual interference. An equation to predict the concentration overpotential of gas evolving electrodes is given. Numerical results are compared with experimental data and show satisfactory agreement. © 1990, The Electrochemical Society, Inc. All rights reserved.
