The bipolar plate is one of the key materials of proton exchange membrane fuel cell (PEMFC), and its cost and performance are hindering the course of commercialization of PEMFC and the improvement of fuel cell performance directly. The performance of artificial graphite bipolar plate is excellent and it is adopted extensively. However, its manufacturing technology is relatively complicated and especially its flow channels can be only machined, so its cost is very high. The researches of various ki...
