A New Bipolar plate of PEM Electrolysis Cell With Uniform Flow and Heat Transfer Fields

Document Type

Conference Proceeding


Optimization of electrolysis cell for producing hydrogen is dependent of a set of complex physical and chemical processes occurring simultaneously. Similar to fuel cells, it has been demonstrated that these processes are strongly dependent on the fluid dynamics inside the fuel cell. Bipolar plates are important components of PEM electrolysis cells because they are the first stage of the flow distribution system. A non-uniform flow distribution across the bipolar plate surface area will probably lead to an unbalanced use of the precious catalyst, and an overall efficiency of the device lower than expected. In the present work a new design of bipolar plate for the PEM electrolysis cell was proposed and 3-D CFD modeling was preformed. Velocity, temperature and pressure distributions within the bipolar plate were investigated. Numerical simulations showed that the flow uniformity within the designed bipolar plate is greatly improved compared with the baseline bipolar plate for water electrolysis.
