Abstract

Hydrogen fuelled proton exchange membrane fuel cells (PEMFCs) are used in a range of transport applications to convert fuel into power with a high efficiency, producing only water as a by-product. Devices in real applications typically take the form of ‘stacks’ - tens to several hundred individual cells stacked together in electrical series to produce useful amounts of power. New materials, cell designs, operating conditions, manufacturing processes etc. are often validated by testing ‘short stacks’ of 5 to 20 cells with cell designs and manifolds identical to those in final devices. Testing at this scale therefore bridges the highly experimental and industrially useful and is therefore highly relevant. Nevertheless, there are limited practical resources available to those wishing to perform measurements on short stacks. This chapter will provide a guide for characterising the behaviour fuel cell short stacks, outlining the principles, facilities, operating conditions, techniques, and considerations necessary to characterise a short stack with accurate and precise measurements.
