dc.description.abstractThe effects of various design and operating variables on the performances of a PEM fuel cell were investigated. Performance was evaluated in terms of the polarization curves (cell potential versus current density plots). The specific effects that were investigated were : (i) effects of scale up from 5 cm 2 to 50 cm2 single cells and stacking 50 cm2- single to multicell (quad cells) stack; (ii) the performance of self humidified single and multicell stack PEMFCs with various electrode structures, platinum loadings and membranes; and (iii) light weight bipolar plates in PEMFCs. Several types and two sizes of PEMFCs were constructed and evaluated. Most membrane and electrodes assemblies (MEAs) were fabricated in-house but some specialized MEAs were provided by an outside source. Polarization plots were made for each PEMFC and the data was correlated using the five parameter empirical equation.en_US
