PowerCell finalizes the development of its 2nd gen fuel cell stack for automotive and stationary applications
3 February 2014
Sweden-based fuel cell technology developer PowerCell (earlier post) is in the final stage of development of its next generation fuel cell stack platform, the S2. The S2 covers a larger power range up to 25 kW and maintains the same tolerance towards CO and reformate gas as the present platform, the S1. The new fuel cell will have good stability and a compact and robust design for both automotive and stationary applications, the company says.
PowerCell’s fuel cell stack is designed to work in an auxiliary power unit (APU) environment on reformate gas as well as on a variety of systems running on pure hydrogen, for both automotive and stationary applications. It uses thin metal bipolar plates and advanced membrane electrode assembly (MEA) in a design prepared for serial production from the start.
The S2 platform will complement the first generation fuel cell stack, the S1 (1-5 kW), as it covers a larger power range up to 25 kW, still with the same tolerance towards CO and reformate gas. The S2 uses proton exchange membrane (PEM) technology and is the choice for automotive applications.
PEM characteristics allow for full power output within seconds. Another feature is the capability for extensive starts and stops, meaning that battery buffers can be kept to a minimum.
PowerCell is a spinout from the Volvo Group with the objective to develop and produce environmentally friendly power systems based on a unique fuel cell and reformer technology that matches existing fuel infrastructures. PowerCell is based in Gothenburg and is owned by Volvo Group Venture Capital, Fouriertransform, Midroc New Technologies and Finindus.
