Researchers demonstrate use of 3D printing to produce and operate light-weight, low-cost electrolyzers

Green Car Congress

A team at the University of Glasgow has demonstrated the production and operation of a PEM electrolyzer constructed from silver-coated 3D-printed components fabricated from polypropylene. The use of 3D printing allows construction of light-weight, low-cost electrolyzers and the rapid prototyping of flow field design.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

Researchers at the University of Exeter (UK) have developed a novel p-type LaFeO 3 photoelectrode using an inexpensive and scalable spray pyrolysis method. These findings demonstrate that LaFeO 3 is a potential candidate to act as a photoelectrode for unassisted PEC water splitting to generate solar fuel (hydrogen) cost effectively.

University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. Different sources of light were used, ranging from a laser to white light simulating the solar spectrum.
