TECO 2030 announced the completed production of the fuel cell stack developed and purposely designed for heavy-duty and marine applications. A fuel cell stack consists of a number of individual stack cells, each generating electricity from electrochemical reactions based on fuels such as hydrogen. TECO 2030's fuel cell stack contains a few hundred stack cells and provides a net output of 100 kW.

The stacks are then combined together with balance of plant (BoP) components into a fuel cell module. TECO 2030 plans to assemble and test the first FCM400 (Fuel Cell Module 400 kW) during the summer of 2023 at AVL's s facility in Graz, Austria. Several modules, in turn, can be combined to supply the megawatts of output needed for applications such as ship propulsion, auxiliary power and other heavy-duty applications.
