Abstract

For high efficiency of PEM fuel cell, bipolar plate needs further improvement contact resistance between bipolar plates as well as between bipolar plate and gas diffusion layer. Common bipolar plates of PEM fuel cell are used to two plates between membranes due to water flow channel. In this study, polymer composite coated metal bipolar plate of all-in-one type is fabricated and compared to common bipolar plate. The bipolar plate of all-in-one type is attached two metal plates that use polymer composite adhesive. Carbon black is used as conducting filler in polymer composite. The optimum composition of polymer composite and fabricating process are investigated. The electrical contact resistance of bipolar plate of all-in-one type are tested and compared to common bipolar plate. The bipolar plate of all-in-one type is minimized contact resistance between plates.
