The StasHH Fuel-Cell Module Standard

This paper describes and motivates a standard for heavy-duty hydrogen fuel-cell modules in terms of their form factors and interfaces, both physical and digital. The goal is that the standardised fuel cell modules shall be suitable for multiple applications such as ships, trains, stationary generator sets in addition to heavy duty vehicles. While standards have been developed for test protocols, safety, and fuelling operations, little to no work has been done to define an interchangeable standard for fuel-cell modules. Such a standard can prove decisive to pool several heavy-duty markets together, accelerate design and realisation of hydrogen vehicles, enable competition among fuel-cell module manufacturers, and reduce their total cost of ownership. The StasHH project is developing prototypes from eight major manufacturers and will test them during 2023.
