The Electrochemical Society of Japan (ECSJ; 公益社団法人電気化学会) is a public interest incorporated association founded in 1933 as the Electrical Chemistry Association. It was officially incorporated in 1935 and renamed ECSJ in 1996.
The society promotes research in the fundamentals and applications of electrochemistry, advances related industrial technologies, and contributes to academic and societal progress. Activities include hosting annual spring and fall meetings, joint international conferences such as PRiME with The Electrochemical Society (USA), publishing journals like Electrochemistry (since 1999) and Denki Kagaku (since 2018), conducting surveys, international collaborations, and public outreach.
ECSJ offers various membership categories for researchers, students, and organizations from academia and industry in fields like batteries, materials, electronics, and surfaces. It presents awards including the Society Award (Takei Award), Academic Award, Technical Award (Tanahashi Prize), and others at its spring convention, recognizing contributions to electrochemistry.
Also known as 電気化学協会.
Pilot alkaline water electrolysis plants demonstrated long-term stable, multi-module operation, proving durability under variable renewables and enabling scale-up toward >100 MW systems
Pilot plants in Namie (since Mar 2020) and Kawasaki (Mar 2024) validated stable alkaline electrolysis, tested 4x0.8 MW multi-modular units for grid response and durability, aiming >100 MW
