Performance of PEMFC stack using expanded graphite bipolar plates

Liquid water transport mechanism in the gas diffusion layer

“…In the LBM analysis, the water contact angle of the bipolar plate is assumed to be 80 • [34], and the contact angle of the MPL surface (B1 in Fig. 2) is assumed to be 150 • [35].…”

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

“…Vacuum resin impregnation in CEG sheets was reported as one of the proper methods for the preparation of polymer/EG composite bipolar plates with good physical properties [17][18][19][20][21][22][23]. For example, Ballard Power System Inc. has investigated CEG-based composite bipolar plates and applied them in the fuel cell vehicles [17][18][19].…”

Preparation and properties of thin epoxy/compressed expanded graphite composite bipolar plates for proton exchange membrane fuel cells

“…Another method for the preparation of polymer/EG composite bipolar plates with good physical properties was vacuum resin impregnation in compressed expanded graphite (CEG) sheets [15][16][17][18][19][20]. There have been few literatures about this kind of bipolar plates so far.…”

“…Then the CEG sheet was impregnated with resin and cured. DICP (Dalian Institute of Chemical Physics) and Sunrise Power Co. Ltd. [18][19][20] had also developed polymer/CEG compos-0378-7753/$ -see front matter © 2009 Elsevier B.V.
