IHI Corporation has developed and successfully demonstrated an electric hydrogen turbo-blower, a large-capacity hydrogen recirculation unit that achieves the world’s highest hydrogen circulation volume in its class. This equipment was developed for use in aircraft fuel cells, and has succeeded in achieving a large capacity by employing an ultra-high-speed motor with a proprietary gas bearing.
 Joint Research Center for Electric Architecturehe  was in charge of the characteristic evaluation for this demonstration, and contributed to this success together with Sanei Machine Co., Ltd., an aircraft body manufacturing equipment manufacturer located in Akita Prefecture.
