Researchers develop solid electrolyte for hydrogen-based batteries and fuel cells

Japanese researchers say they have developed a solid electrolyte that could improve the safety, efficiency and energy density of hydrogen-based batteries and fuel cells.

The team at the RIKEN Cluster for Pioneering Research in Japan said the solid electrolyte allowed hydride ions to be transported at room temperature. Genki Kobayashi, Lead Researcher, said the group had “achieved a true milestone.”

Experimenting with lanthanum hydrides, the team found at room temperature it was “impossible to have efficient conduction.” However, upon replacing some of the lanthanum with strontium and a small bit of oxygen, the team achieved its breakthrough.
