Proton Motor Fuel Cell Launches Higher Power Fuel Cell Stack

28 Nov 2013

Proton 2

Proton Motor Fuel Cell GmbH (Proton) has announced the launch of a higher power fuel cell stack, after a 3-year development period. This latest generation of stack has been created in order to access the markets for higher power classes than its current model. The new stack is called PM400 and is currently designed for an output of up to 30 kW.

During development, Proton’s focus was on reducing costs, simplifying installation and extending service life. This has resulted in significantly reduced material costs per kW in comparison to its previous stack generation, whilst at the same time increasing the power density. Over 5,000 operating hours have already been logged at Proton’s test facility with very promising results. It expects to be able to achieve run times far in excess of 10,000 operating hours (at a constant output of >80% of the starting power).

In addition to the fuel cell stack, the associated system peripherals have also been tested and implemented as part of a development project supported by NOW (National Organisation Hydrogen and Fuel Cell Technology). Here, the priority was to ensure simple integration into each customer application, as well as to reduce system complexity in terms of future production costs. The new concepts were successfully implemented, so that savings in pure material costs (in terms of stack power output) of over 65% were achieved compared to current products. The development stages in terms of simplified system installation and the service life tests will continue to be scrutinised in follow-up projects.

The project manager, Mr Hermann Seim, says: ‘With this new stack generation, we have taken a large and successful step into new power classes. In combination with our wealth of experience in multi-stack systems, scales of up to 250 kW in an overall system appear to be both problem-free and realistic. In this development project, our particular focus was the reduction of system complexity and the use of long-proven components to generate a high level of reliability even at the development phase. As the only German company with our own in-house production of hydrogen fuel cells and systems in this power class, we see here a very good basis for industrial stationary and mobile applications of emission-free energy supply.’
