The surface modification of bipolar plate is also …
How Much Does It Cost to Replace a Flexplate
The average cost to replace a flexplate is between $400 and $600. The exact cost will depend on the make and model of your vehicle, as well as the labor costs at your local auto shop. If you are able to do the work yourself, you can save a significant amount of money.
Bipolar plates for PEM fuel cells: A review
A significant part of the PEMFC fuel cell stack is the bipolar plates (BPs) [5], which account for about 80% of total weight and 45% of stack cost [6]. They are designed to accomplish many functions, such as distribute reactants uniformly over the active areas, remove heat from the active areas, carry current from cell to cell and …

A comprehensive comparison of state-of-the-art manufacturing methods for fuel cell bipolar plates …
BPPs for liquid-cooled stacks usually consist of three different flow fields: an anode side opposite a cathode side, which is why they are called bipolar plates and a flow-field for coolant is located in-between those half plates (HPs). Table 1 shows a schematic partial cross-sectional view of a graphitic and metallic PEMFC stack.
Novel Structured Metal Bipolar Plates for Low-Cost …
The metal plate cost is a significant part of the fuel cell stack cost. Figure 1 shows results of the PEM stack cost analysis recently (December 2015) conducted by our team partner Strategic Analysis, Inc. It shows that bipolar plates account for 14 %–27% of the overall stack cost (1,000–500,000 stacks/year using 2015 technology) [1].

Bipolar Plate
Thin metallic bipolar plates of stainless steel were produced as shown in Fig. 10.18 by the EMM fabrication process. The bipolar plate material was SUS 304 stainless steel measuring 4 cm × 4 cm × 0.6 cm. The reactive area was 2 cm × 2 cm.
Parts of a Fuel Cell
These plates, which may be made of metal, carbon, or composites, provide electrical conduction between cells, as well as providing physical strength to the stack. The surfaces of the plates typically contain a "flow field," which is a set of channels machined or stamped into the plate to allow gases to flow over the MEA.
A promising assembled electrode-bipolar plate for redox flow battery
The traditional electrode-bipolar plate configuration relies on the bipolar plate to collect current and mechanically support the carbon felt during the assembly process. However, the high cost and the vulnerability of bipolar plates (35–150 US$ kg −1 ) and other materials constraint the application of redox flow batteries on a large scale.
