Production of polymeric nanocomposite Bipolar Plate for PEM and DMFC fuel cells

The polymer electrolyte membrane fuel cells(PEM and DMFC) are the most promising power sources for stationary and transportation application in the future due to many attractive features. These features include high efficiency, high power density, relative low operating temperature, conventional fuel supply and long life time. In order to make the PEM and DMFC fuel cells more economically feasible, processing and material costs need to be reduced. In a fuel cell stack, the electrically conductive plates are often referred to as bipolar plates because one face contacts the cathode electrode while the opposite face contacts the anode electrode. Each bipolar plate therefore conducts electrical current from anode of one cell to the cathode of the adjacent cell in the stack. Bipolar Plate is a vital component of PEM and DMFC fuel cells, which supplies fuel and oxidant to reactive sites, removes reaction products, collects produced current and provides mechanical support for the cells in the stack.
