2018-9-3 Despite these drawbacks, graphite plates are a popular choice for fuel cell systems, especially stationary applications, where installation space is not a limiting factor. Typical methods used to create their flow fields are extrusion, hot pressing, machining or injection molding.
Metal-Foam Bipolar Plate for PEM Fuel Cells:
The drawbacks of graphite include weight, fabrication inaccuracy, cost, porosity, and brittleness. Open-cell metal foam is investigated as a flow field/bipolar plate and compared to conventional graphite bipolar plates. The complex internal structure of the foam was modeled using an idealized unit cell based on a body center cube.
