Abstract
AbstractThis chapter presents the design, development and testing of a water-cooled Proton Exchange Membrane Fuel Cell (PEMFC) stack. The PEMFC stack consists of ten fuel cells with an active area of 50 cm2 per cell. The steps involved in the design and development are elaborated. The stacks were constructed using a combination of bipolar and mono-polar plates in serpentine gas flow configuration. The temperature produced inside the cell is controlled by supplying cooling water through water plate. The ratio of landing to channel in the bipolar plate is fixed as unity. Experiments were conducted at various temperatures (40, 50 and 60 °C) and different reactant flow rates in order to maximize the power density. The best performance reported for this fuel cell stack obtained to be 303 W at 60 °C.KeywordsBipolar platesPower densityProton exchange membrane fuel cell stackWater plate
