ECS members Edward Brightman and Gareth Hinds of the National Physical Laboratory have developed a novel reference electrode that will aid in the development of hydrogen production technologies for renewable energy storage.
Both Brightman and Hinds will present their work on reference electrodes at the 227th ECS Meeting in Chicago this May. (Get an advanced look at that presentation here.)
Brightman and Hinds’ work deals with polymer electrolyte membrane water electrolysers (PEMWEs), which convert electricity and water into hydrogen and oxygen using two electrodes separated by a solid polymer electrolyte. While scientists have been looking and PEMWEs as a promising technology for some time now, researchers have been stifled in utilizing them due to the expensive catalyst materials needed and the general poor understanding of the degradation of these catalysts.
Now, Brightman and Hinds have tackled this issue by finding a way to produce PEMWEs with a cost-effective design and extended lifetime. This development allows for in situ measurement of the electrochemical process at the anode and the cathode.
