A team of researchers at the Korea Institute of Energy Research (KIER) led by Seo Doo-won (principal engineer of the High Temperature Energy Conversion Laboratory) has developed the technology for manufacturing ‘flat-tubular cells.‘ A flat-tubular cell is a core component of the reversible high-temperature water electrolysis-fuel cell technology and this technology is a promising energy storage technology that generates hydrogen from water by using electric energy and, if necessary, coverts hydrogen into electric energy.

This technology is the first in Korea and is used to manufacture the core component of flat-tubular solid-oxide cells with large active surface area of 100cm2. And it has higher power density per volume while guaranteeing higher efficiency and stability, advantages of flat cells and tubular cells, respectively.

In addition, this technology is expected to contribute to the development of the downstream industry sectors in Korea (such as hydrogen-related materials and components sectors) as it can be transferred to SMEs.
