Three reasons why Ceria is a low-risk choice for SOEC stack manufacturing
Cerium Oxide (CeO2), also known as Ceria, is the key ingredient in our secret recipe for creating best in class solid oxide technology. Not many know of this compound, but it is already used in automotive catalysts and is even in your kitchen if you have self-cleaning oven. Here we provide three reasons why Ceria is an excellent choice to decrease manufacturing risk and placate your supply chain risk managers.
- Abundant rare earth material – starting with an oxymoron. Cerium is classified as a rare earth metal but is known as the most abundant of all of them. Its concentration in Earth’s crust is higher than Lithium. It is widely available in igneous and sand deposits making Ceria an accessible option.
- Geographically spread. Cerium deposits are distributed globally, with significant sources in countries like the U.S, China, Australia, and Brazil. This geographic diversity spares dependency on any single region and enhances supply chain security by mitigating the risk of geopolitical issues or regional disruptions. In comparison, Yttrium is a material primarily sourced from China that may become entangled in anticipated trade tensions.
- Low requirement. Ceres’ steel substrate design enables efficient material utilisation. Our steel substrate design simplifies manufacture and enables extremely thin layering of ceramics that cannot be achieved with electrolyte or fuel-electrode supported designs.
Ceres is named after this wonder-material that we have been working with for the last 23 years. As a global leader in ceria-based electrolytes, we are proud to collaborate with our partners to drive this ground-breaking technology forward.
