As of November 21, 2024, Nimbus Power Systems (Groton, Connecticut, USA) and Toshiba Energy Systems and Solutions Corporation (Kawasaki, Kanagawa, Japan) have signed a joint development agreement for a next-generation pure hydrogen fuel cell stack. [1] It is applicable to various mobility applications, like buses and trucks, as well as stationary uses. Under the agreement, Nimbus will combine its “four-fluid stack technology” with Toshiba’s “fuel cell commercialization and mass production technology” to jointly develop the pure hydrogen fuel cell stack. Nimbus has fuel cell technology aimed at large mobility applications. The “four-fluid stack technology” combines porous and metal separators to supply four fluids: hydrogen, air, pure water, and antifreeze, enabling stable operation at high output. Meanwhile, Toshiba has experience manufacturing fuel cells and possesses commercialization and mass production capabilities using porous separators. Nimbus and Toshiba aim to contribute to the expansion of the hydrogen value chain and decarbonization.
