A Partnership with
Toyota Motor Corporation.
Proven Reliability through
Exemplary Partnership.
An electrolysis system born from the
strengths of two industry leaders
The electrolysis system combines Toyota Motor Corporation’s proprietary fuel cell-based high-efficient and compact cell stack, its quality management and mass-production technologies with Chiyoda’s proprietary plant engineering and modularization technologies.
A 5MW commercial-demonstration unit at Toyota's Honsha Plant which has been launched in 2026 also supports service and maintenance training.
