Development of preform moulding technique using expanded graphite for proton exchange membrane fuel cell bipolar plates

The preparation technique optimization of epoxy/compressed expanded graphite composite bipolar plates for proton exchange membrane fuel cells

“…However, the main handicap of the metal-based bipolar plates is the lack of ability to combat corrosion in the harsh acidic and humid environment of PEMFCs and the considerable power degradation that may be caused by metal ions [1][2][3][4][5][6][7]. Compared with the metal-based bipolar plates, the carbonbased bipolar plates have higher corrosion resistance and lower contact resistance, but they are considered as brittle and permeable to gases [7][8][9][10][11][12][13][14][15]. To develop suitable materials for bipolar plates on the applications in fuel cells, the physical and electrical properties of the bipolar plates should meet the following design requirements (shown in Table 1) [7,16].…”

A Review of Thermoplastic Composites for Bipolar Plate Materials in PEM Fuel Cells

“…To reach target electrical conductivity, a high load of graphite (60-80 wt%) was must be formulated for the bipolar plate material. For example, the graphite composite bipolar plates in the research of Heo and his collaborators were composed of expanded graphite, graphite flake and a novolak-type phenol resin, with a 75:25 wt% ratio of graphite to phenol [29] . The production involved pre-curing and compression moulding processes.…”

A Low-Density Graphite-Polymer Composite as a Bipolar Plate for Proton Exchange Membrane Fuel Cells

“…Table 1 shows the properties of a commercially available bipolar plate [10][11][12][13][14][15][16][17] compared to the plate developed in the present work. These previously reported bipolar plates do not satisfy all of the properties necessary for a bipolar plate.…”
