A green path for proton exchange membrane electrolysers
Electrolysis is the process of using electricity to split water into hydrogen and oxygen. The increased interest in green hydrogen – produced by water electrolysis using renewable energy as source of power – is increasing the need for proton exchange membrane (PEM) water electrolysis. In this context, the EU-funded AdIrCAT project will develop the emerging atomically dispersed metal iridium (Ir) catalysts, which will maximise the utilisation of Ir and significantly improve the mass activity of Ir catalysts. A method will also be developed that potentially allows for upscale production of atomically dispersed Ir catalysts. The success of this project will benefit the widespread deployment of PEM electrolysers and make electrolysed hydrogen fuel economically competitive.
