Shared Reactant Stack

A novel PEMFC stack was designed, assembled and experimentally validated. The fuel cell architecture lead to the removal of the bipolar plate (BPP) and instead a series of chambers that supply a reactant gas to two cells simultaneously.

This concept can result in the reduction of overall stack cost and weight via; alternative material choices for the shared cathode/anode flow field and current collection plate, and reactant manifold supply design.

Characterisation has shown that the stack can yield outputs similar to current fuel cell stacks with a maximum power output of 234 W for 6 cells, equating to a power density of 0.390 W/cm2.

Working with the University of Hertfordshire, School of Engineering and Technology via a Knowledge Transfer partnership (KTP), EES designed and produced an automated demonstrator of fuel cell systems, with application to a range of products including micro-combined heat and power (m-CHP). An expert system design suite was developed, that can take various application specifications and transfer them to a suitable package of control system, which can then be transferred to the control board of a given system.

The project also allowed EES to acquire the new expertise needed in control and health monitoring techniques to move to the next stage of product development and commercialisation.
