RuO2 supported on Sb-doped SnO2 nanoparticles for polymer electrolyte membrane water electrolysers

Electrolysis represents the only commercially developed method for generation of hydrogen from a renewable energy source such as wind or photovoltaics. Polymer electrolyte membrane electrolysers represent the best option for variable power operation at high current loads. This paper reports on the characterisation of electrode and cell performance data for new oxygen evolution catalysts that offer some of the best performance reported at a low operating cell voltage.
