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.

R&D of Electrocatalyst for Polymer Electrolyte Membrane Electrolysis Cell(PEMEC※2)
Toshiba has developed a unique laminated catalyst structure ACLS※3 for PEM electrolyzer, and succeeded in significantly reducing precious metals by improving gas and water diffusivity.

ACLS Manufacturing process

ACLS performance
A precious metal "Iridium" has been reduced to 1/10 of the conventional level.

It enables the cost reduction of water electrolyzer and contributes to the realization of a hydrogen society.
