...Anthony C. Okafor; Hector-Martins C. Mogbo In this paper, the effects of gas flow rates and catalyst loading on polymer electrolyte membrane fuel cell (PEMFC) performance was investigated using a 50 cm 2 active area fuel cell fixture with serpentine flow field channels machined into poco graphite...

... for bipolar plates are primarily graphite and metal. Search for alternative materials to improve weight and cost considerations is needed. This paper discusses the results of an investigation of two elastomeric materials being developed for bipolar plate applications. Perceived advantages of the use...

... (PS) as the polymer matrix phase and an appropriate mixture of carbon black (CB) and graphite (GR) as the conductive additives. Final GDL porosity, especially macroporosity, was generated by selective extraction of the PS phase using adequate solvents. Since the generation of pores was found...
