The effect of mold pressing pressure and composition on properties of nanocomposite bipolar plate for proton exchange membrane fuel cell By Mohammad Jafar Hadianfard Investigation on the corrosion resistance of carbon blackgraphite-poly(vinylidene fluoride) composite bipolar plates for polymer electrolyte membrane fuel cells
Aug 23, 2011 · Bipolar plates in the PEMFC have traditionally been made from graphite, since graphite has excellent chemical stability to survive the fuel cell environment. Other advantages of graphite are its excellent resistance to corrosion, low bulk resistivity, low specific density, and low electrical contact resistance with electrode backing materials. Bipolar Plates - Schunk Carbon TechnologyBoth are valued by leading fuel cell manufacturers across the globe, a fact reflected in the more than 700,000 plates produced to date. Our bipolar plates are characterized by a very high proportion of graphite, which achieves outstanding electrical conductivity, as well as corrosion resistance, mechanical strength and flexibility.
Bipolar Plates / Composite Graphite Plates. Dura-SLATE® brand Graphite Composite Bipolar Plates are highly conductive and corrosion resistant at high temperatures. These plates can be machined on both sides to be used as bi-polar plates. The materials used in production allow for very high fuel cell Carbon Composite Bipolar Platesthe bipolar plate providing an electrode for the cells on either side. The reference material for the bipolar plate is high-density graphite with machined flow channels. Both material and machining costs for graphite, however, are prohibitive for many fuel cell applications, and this has led to substantial development efforts to replace

Product Details. Fuel Cell Bipolar Plates The fuel cell bipolar plates developed by Kimwan adopt a new type of binder in the processing, so that the fuel cell bipolar plates have excellent electrical conductivity and corrosion resistance, high mechanical strength and good gas seal. Thanks to the direct hot press forming method, the production process is simplified and the processing cost is Corrosion of metal bipolar plates for PEM fuel cells:A Apr 01, 2010 · In a fuel cell stack the bipolar plates are key elements as they account for large fractions of the total weight, volume and cost of the stack. According to Tsuchyia and Kobayashi  bipolar plates may reach up to 80% of the total weight and 45% of the total cost in a PEM fuel cell stack. More recent data show that the relative cost has fallen to about 25% of the stack , yet a very significant amount.
50% of the system, and the bipolar plate costs represent 25% of the fuel cell stack costs, each plate must cost less than $0.0045/cm 2, including both material and fabrication costs. For plates with a surface area of 400 cm 2, this sets cost to about $1.35 / plate. Milling of individual plates Effect of Terminal Design and Bipolar Plate Material on Fuel cell performance can be greatly affected by the cell internal resistance. Different bipolar plate materials and fuel cell terminal structure designs can affect the cell in- ternal resistance. Figure 3. shows the cell internal re- sistance measurement of 50 cm. 2. active area single cells with different bipolar plate materials namely coated
