Abstract:A laser processing technique is proposed for the processing of a 2.5mm thick carbon nanotube (CNT) composite bipolar plate for proton exchange membrane fuel cells (PEMFCs). This study aims to understand laser interaction with the CNT composite plate experimentally, using a pulsed nanosecond laser. Penetration depth, top width, spatter width and overall physical morphologies are studied. Scanning Electron Microscope (SEM) and 3D Scanning Confocal Microscope were used for observation and measurements. Based on t… Show more
