A joint research team, affiliated with UNIST has introduced the Hybrid-Solid Electrolysis Cell (Hybrid-SOEC) system with highest reported electrochemical performance in hydrogen production. The proposed system has attracted much attention as a new promising option for the cost-effective and highly-efficient hydrogen production, as it shows excellent performance compared with other water-electrolysis systems.
This breakthrough has been led by Professor Guntae Kim in the School of Energy and Chemical Engineering at UNIST in collaboration with Professor Tak-Hyoung Lim of Korea Institute of Energy Research (KIER) and Professor Jeeyoung Shin of Sookmyung Women's University.
A solid oxide electrolyzer cell (SOEC) consists of two electrodes and an electrolyte that are all in solid-state. They are strongly desired as novel candidates for the hydrogen production, as they require no need to replenish lost electrolytes, while eliminating the corrosion problems. Besides, SOECs also operate at relatively high temperatures (700-1000 °C), which helps to offer reduced electrical energy consumption.
Professor Kim and his research team have been seeking ways to improve energy efficiency of hydrogen production, using SOEC. In the study, the research team has demonstrated the novel concept of Hybrid-SOEC based on the mixed ionic conducting electrolyte, allowing water electrolysis to be occurred at both hydrogen and air electrodes.
[...] The layered perovskite with excellent electrochemical properties was used as the electrode of Hybrid-SOEC. By adding an excellent electrode material on mixed ionic conducting electrolyte, resulting in enhanced electrochemical performance. As a result, the corresponding yields of hydrogen produced were 1.9 L per hour at a cell voltage of 1.5 V at 700 °C. This is four times higher hydrogen production efficiency than the existing high-efficient water electrolytic cells.

I'm of mixed opinions about this. On one hand, if he's trying to use fraud or something else to trick money from others, it's shameful and they should be shamed. On the other hand, most basic research doesn't have very much obvious immediate practical use, and I think basic research is substantially underfunded in general.
This "not in a million years" could inspire something something which is "not in a thousand years," which in turn inspires something for the "maybe in 20 years with dedicated funding" which turns into a "getting electricity is easy; just plug your lamp into the mains." Or it could turn into a flop dead-end. I think it's worth at least some effort to try out... certainly more than another scanner in the airport or another subsidy to (insert industry here).
