Both daily and seasonal fluctuations of renewable power sources will require large-scale energy storage technologies. A recently developed integrated battery electrolyzer system, called battolyser, fulfills both time-scale requirements. Here, we develop a macroscopic COMSOL Multiphysics model to quantify the energetic efficiency battolyser prototype that, for first time, integrates functionalit...

As an important energy carrier in terms of carbon neutrality, green hydrogen produced by water electrolysis using renewable electricity has attracted worldwide attention. The polymer electrolyte electrolyzer (PEWE) the potential to be a mainstay market future because its superior performance. However, development PEWE is constrained slow progress membrane electrode assembly (MEA), which essenti...
