Introduction    

OxySep is a subunit within the SINEWAVE project that is worked together by TU Dresden and HZDR. OxySep deals with the optimization of oxygen separation and heat transfer in the anode circuit of the new generation of PEM electrolysers. The high current density leads to a high gas content. This enters new and hitherto misunderstood operating ranges characterized by altered bubble formation due to high supersaturations, large gas contents and significant temperature increases in the ultrapure water.
