A Competitive Design and Material Consideration for

Several bipolar plate fabrication techniques have been utilized in the past for the fabrication of PEM fuel cell bipolar plates. Heo et al. [5] developed a preform molding technique for manufacturing expanded graphite (EG) bipolar plates for PEM fuel cells. Dhakate et al. [6] used a compression molding Bipolar Plate - an overview ScienceDirect TopicsBilal Abderezzak, in Introduction to Transfer Phenomena in PEM Fuel Cell, 2018. 1.3.1.4 Bipolar plates. Bipolar plates are made of graphite or metal; they evenly distribute the fuel and the oxidant to the cells of the fuel cell. They also collect the generated electric current at the output terminals. In a single-cell fuel cell, there is no bipolar plate; however, there is a single-sided plate
