The trend toward renewable energy and the quest for alternative energy sources is gradually expanding due to the increasing demands of humanity and developing industrial processes. Hydrogen energy is a clean energy source and research into electrolysis, which is one of the clean hydrogen production technologies, is becoming more important. The proton exchange water electrolyser, which is one of the electrolyser types, is the focus of this research. Using COMSOL Multiphysics commercial software, CFD analysis is completed at two different temperatures, 20â and 80â, with 3,18,23 electrode channels of PEMWE. The results of the oxygen volume fraction, velocity, and pressure on the anode side, which occurred at different times, were evaluated using a mixture model combining water and oxygen. It is observed that the PEM electrolyser cell performed more efficiently at 80â. The accuracy of the data is confirmed through comparisons with similar study examples. |
