New technology contributes to carbon neutrality

• 

Toshiba is conducting research and development aimed at realizing a next-generation hydrogen society and is striving to improve the economic efficiency of each phase of the production, storage, and use of hydrogen.

R&D of Solid Oxide Electrolysis Cell(SOEC^*1)

Toshiba has achieved high hydrogen production efficiency by developing original materials for hydrogen generating electrodes.

In addition, by controlling the hydrogen and oxygen electrode structures and the electrode / electrolyte interface structure, we have succeeded in reducing the deterioration rate and extending the service life.
