Proposed DWE process. Schematic illustration of the proposed DWE process with continuous generation of H2 and O2 in separate electrolytic and catalytic cells using Br–/BrO3– as a soluble redox couple. The oxidized bromate-rich (BrO3–) electrolyte flows from the bottom of the electrolytic cell to the bottom of the catalytic cell, where it is reduced to bromide (Br–) by a catalyst and flows from the top of the catalytic cell back to the top of the electrolytic cell. The green coating represents a semipermeable chromium hydroxide layer. Credit: Nature Materials (2024). DOI: 10.1038/s41563-023-01767-y

Solid oxide fuel cells (SOFC) are widely used for energy storage, transportation, and various applications, employing solid electrolytes such as ceramics. The efficiency of these cells relies on the performance and stability of their electrodes.

To enhance this efficiency, there is a requirement to fabricate electrodes with a porous structure. Unfortunately, existing technologies face challenges in achieving a uniform coating of ceramic materials within electrodes possessing intricate porous structures.

A collaborative research team, comprising Professor Jihwan An and Ph.D. candidate Sung Eun Jo from the Department of Mechanical Engineering at Pohang University of Science and Technology (POSTECH), and others, has successfully produced porous electrodes for SOFCs using latest semiconductor processes. This research has been featured as a back cover article in Small Methods.

The process

New Technology Could Bring Hydrogen Into The Mainstream

New Technology Could Bring Hydrogen Into The Mainstream

One of the world’s biggest challenges is slashing emissions before it’s too late. In fact, we’ve only got until 2050 in order to avoid some of the worst effects of climate change. And guess what? Asking people to ditch meat isn’t going to be enough.

Even a drastic reduction in the use of fossil fuels alone won’t stop the Earth from reaching a point of no return.

Solutions must come from every corner of the world, and cover every major industry and the power and process they use. And they need to come fast.

That’s why the energy transition is a race that can only be won by the most advanced technologies and engineers with unique minds for creative solutions.

Otherwise, we risk getting caught in a loop of perpetual motion with respect to greenhouse gas emissions.

The story of hydrogen has been a cautionary tale to this end.
