Watts Up With That? by Eric Worrall 11/4/2020
Researchers in Spain claim their breakthrough cuts the cost of electrolysis cells, by replacing the traditional arrangement of layered electrode plates with a much simpler electrochemical system.
H2? Oh! New water-splitting technique pushes progress of green hydrogen
It’s really dope. Yep it’s an energy-efficient process kicked off by gadolinium-doped cerium dioxide

Researchers in Spain have uncovered a new approach to producing hydrogen via water splitting which could help overcome some of the drawbacks to this promising alternative fuel source.
In a study published in Nature Energy, Valencia University researcher José Manuel Serra, professor José M Catalá-Civera, and their colleagues describe a method for producing hydrogen gas by blasting microwave radiation at a watery chemical soup. The approach could make extracting hydrogen from water cheaper, and more importantly, reduce the capital costs of the necessary machinery. …
The cyclical process proposed by the research team uses a soup of gadolinium-doped cerium oxide and water. Applying microwaves to the mixture electrochemically deoxygenates the cerium oxide, but when the microwaves stop, there’s a reaction with the water, and the cerium re-oxygenates and produces free hydrogen.
